Weak Mexican government is to blame not the U.S.  When there is an internal conflict such as this it is almost always a weak government that is to blame for not preventing an escalation of violence. The government is to blame as it is meant to have a monopoly on the use of force, conflicts such as this drugs war occur when that monopoly on violence is broken. In Mexico the election of Vicente Fox as president may have been a democratic triumph for ending the 70 year one party rule by the P.R.I. but in terms of the effectiveness of the central government it was not a success. The National Action Party has been weak in the lower house and senate so unable to advance a legislative agenda. [1] An inability to legislate significantly reduces the ability of the federal government to respond to the drugs crisis. This reduces the ability of the Federal government to step in and sort out local problems. There has been an upsurge of social unrest of all types, not just drugs violence but protests, riots and strikes as well. [2]  Drugs traffickers have taken over many local areas, the local government, police and even some of the army has been penetrated by the drugs traffickers. This leaves the local government unable to do anything against the traffickers. It was not the drugs traffickers who created the institutional problems that allowed the government to become penetrated in the first place; corruption, inefficient police forces and a weak judiciary were already a problem.
