of one is the concern of all, and therefore commits to a collective response to threats to, and
breaches of peace. Collective security is more ambitious than systems of
alliance security or
collective defense in that it seeks to encompass the totality of states within a region or indeed globally, and to address a wide range of possible threats. While collective security is an idea with a long history, its implementation in practice has proved problematic. Several prerequisites have to be met for it to have a chance of working. It is the theory or practice of states pledging to defend one another in order to deter aggression or to target a transgressor if international order has been breached.

Perpetual Peace: A Philosophical Sketch''. Kant outlined the idea of a league of nations that would control conflict and promote peace between states. However, he argues for the establishment of a peaceful world community not in a sense that there be a
global government but in the hope that each state would declare itself as a free state that respects its citizens and welcomes foreign visitors as fellow rational beings. His key argument is that a union of free states would promote peaceful society worldwide: therefore, in his view, there can be a perpetual peace shaped by the international community rather than by a world government.

In a 1945 ''American Political Science Review'' article,
Frederick L. Schuman criticized notions that a new collective security organization could contribute to world peace. Schuman pointed to examples from history of collective security organizations that failed to facilitate world peace. He argued that the organization that would become the United Nations could only facilitate world peace if the United States, the Soviet Union, and the United Kingdom worked in unison, but that the organization would fail if there were divisions between the three powers.
Theory
Collective security can be understood as a security arrangement in which all states cooperate collectively to provide security for all by the actions of all against any states within the groups which might challenge the existing order by using force. That contrasts with self-help strategies of engaging in war for purely-immediate national interest. While collective security is possible, several prerequisites must be met for it to work.
Collective security also contrasts with
alliance
An alliance is a relationship among people, groups, or states that have joined together for mutual benefit or to achieve some common purpose, whether or not explicit agreement has been worked out among them. Members of an alliance are called ...
s by different ways. In a Ph.D dissertation by Andreatta, collective security is based on the perspective of all together in a group against any of them, rather than on
unilateral idea of some against specific others.
Alliances have the form of two groups against each other, such as states A+B+C against states Y+Z; however, collective security takes the form of conducting one agreement between A+B+C+Y+Z against any of them. Moreover, it is also different from an alliance since collective security is made to focus on internal regulation required universal membership, but alliance is made to deter or reduce an outside threat as an exclusive institution. In an alliance, a state would see its allies as an
absolute gain and its enemies as a
relative gains without
legal obligation
The law of obligations is one branch of private law under the civil law legal system and so-called "mixed" legal systems. It is the body of rules that organizes and regulates the rights and duties arising between individuals. The specific rights ...
. In contrast, collective security follows the case of neutrality, as the whole group is required to punish the aggressor in the hope for it not to violate general norms, which are beyond the states' control, rather than by their self-interest. The opposite of short-term interest in which allies fight against a common threat, collective security tends to use universal interests for
global peace.
Sovereign nations eager to maintain the status quo willingly co-operate and accept a degree of vulnerability and, in some cases for minor nations, also accede to the interests of the chief contributing nations organising the collective security. It is achieved by setting up an international co-operative organisation under the auspices of international law, which gives rise to a form of international collective governance, despite being limited in scope and effectiveness. The collective security organisation then becomes an arena for diplomacy, the balance of power, and the exercise of soft power. The use of hard power by states, unless legitimised by the collective security organisation, is considered illegitimate, reprehensible, and necessitating remediation of some kind. The collective security organisation not only gives cheaper security but also may be the only practicable means of security for smaller nations against more powerful threatening neighbours without needing to join the camp of the nations that balance their neighbours.

. By employing a system of collective security, the United Nations hopes to dissuade any member state from acting in a manner likely to threaten peace and thus avoid a conflict.
Collective security selectively incorporates the concept of both
balance of power and
global government. However, collective security is not the same as the balance of power, which is important in
realism. According to Adreatta, the balance of power focuses on a state's unilateral interests in stopping aggression. Since states look at the world as having a security dilemma because of the fear of relative gain, a state does not want any state to become predominant and so causes a mutually-restraining equilibrium. In other words, the balance of power between states supports the decentralization of power. States are separate actors and do not subordinate their
autonomy

or sovereignty to a central government. "Singly or in combinations reflecting the coincidence of interests, States seek to influence the pattern of power distribution and to determine their own places within that pattern." The expectations of order and peace come from the belief that competing powers will somehow balance and thereby neutralize one another to produce "deterrence through equilibration."
[Claude, p. 222] In contrast, under collective security, states share the long term goal of global peace, reversing relationship between individual and community goals mentioned in the balance of power theory, which fails to maintain stability. For example, it led to break down of war during the case of Napoleonic Wars and the World Wars, when states unilaterally decided to be unwilling or unable to fight.
At the same time, the concept of global government is about centralization. Global government is a centralized institutional system that possesses the power use of force like a well-established sovereign nation-state. The concept strips states of their "standing as centers of power and policy, where issues of war and peace are concerned"
and superimposes on them "an institution possessed of the authority and capability to maintain, by unchallengeable force so far as may be necessary, the order and stability of a global community."
Despite different characteristics of balance of power theory, collective security selectively incorporates both concepts, centralization and decentralization, which can boil down to the phrase "order without government." Thus, collective security seems to be more reliable alternative since it gathers power as a team to punish the aggressor, and it is an attempt to improve international relations and to provide solid rules under
anarchy.
Basic assumptions
Organski (1960) lists five basic assumptions underlying the theory of collective security:
* In an armed conflict, member nation-states can agree on which nation is the aggressor.
* All member nation-states are equally committed to contain and constrain the aggression, irrespective of its source or origin.
* All member nation-states have an identical freedom of action and ability to join in proceedings against the aggressor.
* The cumulative power of the cooperating members of the alliance for collective security is adequate and sufficient to overpower the might of the aggressor.
* In the light of the threat posed by the collective might of the nations of a collective security coalition, the aggressor nation will either modify its policies or be defeated.
Prerequisites
Morgenthau (1948) states that three prerequisites must be met for collective security to successfully prevent war:
* The collective security system must be able to assemble military force in strength greatly in excess to that assembled by the , thereby deterring the from attempting to change the world order that is defended by the collective security system.
* Those nations, whose combined strength would be used for deterrence as mentioned in the first prerequisite, should have identical beliefs about the security of the world order that collective security is defending.
* Nations must be willing to subordinate their conflicting interests to the common good defined in terms of the common defense of all member-states.

In both cases, the absence of the United States deprived it of another major power that could have used economic leverage against either of the aggressor states.

in March 1939, Western powers were shown not to be prepared to engage in collective security with the Soviet Union against aggression by Germany.

international community to act in concert (Mingst 1999).

contains stronger provisions for decision-making and collective military action than those of the League of Nations Covenant, but it represents not a complete system of collective security but a balance between collective action and the continued operation of the states system, including the continued special roles of great powers. States in the UN collective security system are selective to support or oppose UN action in certain conflicts, based on their self-interests. The UN can be somehow seen as the platform for self-interest purposes for members in Security Council because of the permanent members' veto power and the excessive assistance or aid, which have made those states to act unilaterally and to ignore the approval of or to violate resolutions of the Security Council. The Iraq crisis is a clearer example: "Rather than seek the global interest of peace and security through stability in Iraq and the Middle East region, the domination oriented members amassed their vast economic, diplomatic and military resources, captured and brazenly subjugated Iraq to an unprecedented condominial regime serving their economic interest under Iraq Reconstruction Programme" (Eke 2007).
In addition, the lack of geographical spread of members in the Security Council causes an imbalance in the role of maintenance global peace and security. The voices of small countries can be heard, but policies are not adopted in response to them unless they serves the great powers' interests.
However, collective security in the UN has not completely failed. The role of the UN and collective security in general is evolving with the rise of

in which other states have intervened in some manner. That means that collective security may have to evolve towards providing a means to ensure stability and a fair international resolution to those internal conflicts. Whether that involves more powerful peacekeeping forces or a larger role for the UN diplomatically is likely to be judged on a case-by-case basis.

Collective defense has its roots in multiparty
alliances and entails benefits as well as risks. On the one hand, by combining and pooling resources, it can reduce any single state's cost of providing fully for its security. Smaller members of NATO, for example, have leeway to invest a greater proportion of their budget on nonmilitary priorities, such as education or health, since they can count on other members to come to their defense, if needed.
On the other hand, collective defense also involves risky commitments. Member states can become embroiled in costly wars benefiting neither the direct victim nor the aggressor. In
