Over time, many of the Zetas' original thirty-one members have been killed or arrested; a number of younger men have filled the vacuum, but the group as currently extant remains far from the efficiency of their paramilitary origins. Los Zetas was partially responsible for a qualitative increase in the brutality of the violence seen during the Modern Mexican Drug Wars. Unlike other cartels, the Zetas did not buy alliances so much as terrorize their enemies. Because the cartel was quite new at the time, it competed with more established cartels by using extreme violence and cruelty as a form of

Split from the Gulf Cartel

Following the capture and extradition of Cárdenas, Los Zetas became so powerful that they outnumbered and outclassed the Gulf Cartel in revenue, membership, and influence by 2010. As a result of this imbalance, the Cartel tried to curtail their own enforcers' influence and ended up instigating a civil war. In addition, the Cartel, through its narco-banners in Matamoros and

Some sources claim that Guillén, brother of Cárdenas and one of the successors of the Gulf Cartel, was addicted to gambling, sex, and drugs, leading Los Zetas to perceive his leadership as a threat to the organization. Other reports mention, however, that the divide occurred due to a disagreement on who would take on the leadership of the cartel after the extradition of Cárdenas. The candidates from the Cartel were Guillén and

, the former second-in-command of Los Zetas, had reportedly taken the leadership of the Zetas and displaced Lazcano. Lazcano was initially content to have Morales in his ranks, but reportedly gave Morales too much power and underestimated his violent nature. Morales' active leadership gained him the loyalty and respect of many in Los Zetas, leading many to eventually stop paying their tributes to Lazcano. Los Zetas are inherently an unstable organized crime group with a long history of brutal violence, and with the possibility of more if the infighting continues and if they fight off without a central command.


Attacks

Los Zetas have also carried out multiple massacres and attacks on civilians and rival cartels, such as: * the 2008 Morelia grenade attacks (15 September), where 8 were killed and over 100 were injured; * the 2010 San Fernando massacre (24 August), where 72 migrants were found dead; * the 2011 San Fernando massacre (6 April – 7 June), where 193 people were killed; * the massacre of 27 farmers in

In mid-2010, both Flores and the mayor of Reynosa, Óscar Luebbert Gutiérrez – both members of the PRI – were criticized for claiming that there were no armed confrontations in Tamaulipas and that the widespread violence was "only a rumor". Months later, Flores finally acknowledged that several parts of Tamaulipas were "being overrun by organized crime violence". Gutiérrez later recognized the work of the federal troops and acknowledged that his city was experiencing "an escalation in violence".


Prison breaks

On 25 March 2010, forty inmates escaped from a federal prison in the city of Matamoros. On 5 April 2010, at a prison in Reynosa, a convoy of ten trucks packed with gunmen entered the prison grounds without resistance, broke into the cells, and liberated thirteen "extremely dangerous" inmates. Eighty-five inmates escaped from the same Reynosa prison six months later. In

As a result, most police forces in Tamaulipas are believed to be susceptible to corruption due to their low wages, and accept bribes from organized crime groups.

The following month, the federal government was asked to send in troops to combat the drug cartels in the area, to "consolidate actions on public safety" and "strengthen the capacity of their institutions". However, the troops could only replace half of the policemen in the state. Consequently, the government is currently building military bases in Ciudad Mier, San Fernando and

Organizational structure and training

training facilities. Los Zetas members may also possess a "Los Zetas Commando Medallion" for their service to the organization. It is reported that Los Zetas also uses women within their organizational structure. There is a female unit known as the ''Panteras'', or panthers. These women use seduction to negotiate with military, law enforcement, and political personnel to help Los Zetas' goals. In the event that they are unable to obtain the desired outcome, they may kill their targets. The initial leader of this group was Ashly "La Comandante Bombón" Narro López; she was captured in 2009 in connection to the murder of General Tello Quiñones. Women also work within the cartel as plaza bosses, administrators, mediators, and shooters.


List of initial members

Arturo Guzman was initially tasked by Cardenas to recruit 20 men to murder his rival Rolando Lopez Salinas. Guzman and Lazcano were eventually able to convince 34 GAFE operators to leave the Mexican Army and form the core of Los Zetas. The first 14 members became known as the "Group of 14" (''Grupo de los Catorce'') or simply "The 14" (''Los 14'').David F.

Rivalries

Indications of the broken alliance between the Gulf Cartel and Los Zetas began in September 2009. On 24 February 2010, gunmen onboard hundreds of trucks marked ''C.D.G'', ''XXX'', and ''M3'' the insignias of the Cartel clashed with Zetas gunmen in the northern cities of Tamaulipas. The clash between these two groups started in Reynosa, and then expanded to Nuevo Laredo and Matamoros. The war then spread out through eleven municipalities of Tamaulipas, nine of them bordering Texas. Soon, the war reached Tamaulipas' neighboring states of

on 5 October 2010. Confrontations between the two groups temporarily paralyzed entire cities in broad daylight. Many of the municipalities throughout Tamaulipas were described by witnesses as "war zones", with many businesses and homes burned down. In the midst of violence and panic, local authorities and media tried to minimize the situation and claimed that "nothing was occurring", but the facts were impossible to cover up. For many years, there were long-fought battles between the Gulf and Sinaloa Cartels, that eventually led the two to reevaluate the situation and decide whether or not this combat was in either organization's best interests. The complexity and territorial advantage of Los Zetas forced the Gulf Cartel to seek an alliance with the Sinaloa Cartel and La Familia Michoacana.


Alliances

Following the conflict with the Gulf Cartel, Los Zetas joined forces with the

Since February 2010, the major cartels have aligned in two factions, one formed by the Juárez Cartel, Tijuana Cartel, Los Zetas and the Beltrán-Leyva Cartel; the other faction integrated by the Gulf Cartel, Sinaloa Cartel and La Familia Cartel.

Thus far, of the resources promised by the United States government regarding Mexico and their ongoing drug combat, little has been received, principally because Mexico's 2012–18 PRI government failed to honor the clause of improving and upholding human rights in the Mexican Federal Republic.


Anonymous' Operation Cartel

The operation to expose information of people who work with Los Zetas, dubbed "Operation Cartel", was reportedly started as a result of an Anonymous (group), Anonymous member being kidnapped during Operation Paperstorm in Veracruz, a once peaceful city. ''The New York Times'' mentioned that Los Zetas has access to sophisticated Computer surveillance, tracking software due to the fact that they have infiltrated Mexican law enforcement agencies, and that online anonymity might not be enough protection for Internet users.


Influence outside of Mexico

Los Zetas have caused terror throughout Mexico for the past two decades. But they also present a threat to all nations in the Western Hemisphere. As of 2017, 40% of Mexico's oil market is under the control of the Zetas. According to the Energy Information Administration, U.S. Energy Information Administration, Mexico is responsible for 10% of all of United States petroleum imports and plays an even larger role in exporting to nations in South America. In the oil industry alone, the influence of Los Zetas has the potential to cause economic instability in every nation Mexico partners with, and many of these nations may not have the economy to be able to withstand this instability. The Zetas also play a role in transporting humans and drugs across borders, providing security to these operations. These drug trades are responsible for providing countries from

Mexico serves as a central location for these organizations to conduct their business and thus gets affected the most, but the effects are seen all along the trade route. In addition to the more common drugs like marijuana and cocaine, the

has reported Los Zetas have also provided support in the fentanyl trade, an extremely potent drug that has been the primary drug causing overdose, with America alone exceeding 100,000 deaths per year by overdose. These harder drugs are shipped to the cartels through partnerships with China and other Asian countries, before being distributed out across the Americas. The constant supply of drugs to all countries in the west can be directly contributed to the Zetas and other major cartels in Mexico, and it will continue to corrupt Mexico's neighbors. The last method Los Zetas use to influence western nations is through criminal rule in prison systems. Los Zetas members have long been known to create a system of criminal governance within prison systems through

Criminal group summary

Los Zetas is a Mexican-based cartel that primarily engages in drug, weapon, human trafficking operations.  They pose a great humanitarian risk to the regional communities and to those in which its activities extend, including several countries in Central America and across the largest cities in the United States.  Since the group has committed torture, executions, and mass murder, it is seemingly identified as a terrorist organization.  Despite this, Los Zetas is characterized as an organized criminal group because it has an expansive membership, has existed over a period of time, and commits serious crimes for the purpose of financial gain.   Los Zetas' original 31 members were soldiers in Mexico's most elite special forces unit, the Grupos Aeromóviles de Fuerzas Especiales (GAFE).  Since the group's inception as a drug trafficking organization, it has recruited soldiers from the Mexican military that train cartel members and lead operations.  The cartel's success is attributed to their military professionalism and extreme use of violence.     At the height of the Los Zetas operation, it was the largest cartel in terms of territorial control.  It was able to gain and maintain its territory across Mexico because of the organization's hierarchical structure—this reflects organized crime's theoretical perspective of the bureaucracy model.  Los Zetas divides its roles and responsibilities along strategic, operational, and tactical lines which allow them to effectively combat rival cartels and engage in illicit activities. Although Los Zetas does not have control over Mexico's political institutions, it has breached Mexico's law enforcement institutions.  The cartel has corrupted hundreds of local and state security officials by offering them bribes and threatening them with death.  As a result, Los Zetas has been able to freely engage in illicit activities without being impeded by police in those areas. In the last decade, however, Mexico has received money from the United States to better resource their military.  Since then, the government has made great steps to destabilize and fragment the Los Zetas.
