Last week we discussed the impact that crime, and specifically kidnapping, has been having on Mexican citizens and foreigners visiting or living in Mexico. We pointed out that there is almost no area of Mexico immune from the crime and violence. As if on cue, on the night of Feb. 21 a group of heavily armed men threw two grenades at a police building in Zihuatanejo, Guerrero state, wounding at least five people. Zihuatanejo is a normally quiet beach resort just north of Acapulco; the attack has caused the town’s entire police force to go on strike. (Police strikes, or threats of strikes, are not uncommon in Mexico.)

Mexican police have regularly been targeted by drug cartels, with police officials even having been forced to seek safety in the United States, but such incidents have occurred most frequently in areas of high cartel activity like Veracruz state or Palomas. The Zihuatanejo incident is proof of the pervasiveness of violence in Mexico, and demonstrates the impact that such violence quickly can have on an area generally considered safe.

Significantly, the impact of violent Mexican criminals stretches far beyond Mexico itself. In recent weeks, Mexican criminals have been involved in killings in Argentina, Peru and Guatemala, and Mexican criminals have been arrested as far away as Italy and Spain. Their impact — and the extreme violence they embrace — is therefore not limited to Mexico or even just to Latin America. For some years now, STRATFOR has discussed the threat that Mexican cartel violence could spread to the United States, and we have chronicled the spread of such violence to the U.S.-Mexican border and beyond.

Traditionally, Mexican drug-trafficking organizations had focused largely on the transfer of narcotics through Mexico. Once the South American cartels encountered serious problems bringing narcotics directly into the United States, they began to focus more on transporting the narcotics to Mexico. From that point, the Mexican cartels transported them north and then handed them off to U.S. street gangs and other organizations, which handled much of the narcotics distribution inside the United States. In recent years, however, these Mexican groups have grown in power and have begun to take greater control of the entire narcotics-trafficking supply chain.

With greater control comes greater profitability as the percentages demanded by middlemen are cut out. The Mexican cartels have worked to have a greater presence in Central and South America, and now import from South America into Mexico an increasing percentage of the products they sell. They are also diversifying their routes and have gone global; they now even traffic their wares to Europe. At the same time, Mexican drug-trafficking organizations also have increased their distribution operations inside the United States to expand their profits even further. As these Mexican organizations continue to spread beyond the border areas, their profits and power will extend even further — and they will bring their culture of violence to new areas.

The spillover of violence from Mexico began some time ago in border towns like Laredo and El Paso in Texas, where merchants and wealthy families face extortion and kidnapping threats from Mexican gangs, and where drug dealers who refuse to pay “taxesâ€
