Decades of drug war demolition tactics have taken their toll on our diplomacy in South America:

QUITO (Reuters) - From Argentina to Nicaragua, Latin Americans have elected leftist leaders over the last decade who are challenging Washington's aggressive war on drugs in the world's top cocaine-producing region.

These governments are shaking off U.S. influence in the region and building defense and trade alliances that exclude the United States. Some now say they can better fight drugs without U.S. help and are rejecting policies they do not like.

The strongest resistance to U.S. drug policies is in Ecuador and Bolivia, two coca-growing countries of the Andes, and in Venezuela.

This is just the inevitable consequence of bribing foreign governments to let our soldiers run around on their land slashing and burning the livelihoods of impoverished populations. We've declared war on the coca plant itself, insisting that it not be grown even by indigenous people who've used it for thousands of years for altitude sickness and appetite suppression. As it becomes increasingly clear that none of this is accomplishing anything, everyone's starting to realize that we have no intention of ever leaving.

We literally go around giving report cards to sovereign nations rating their cooperation in our own hopeless effort to stop Americans from using drugs. Both sides in the South American drug war are funded with U.S. dollars, yet we bare only the burden of our own indulgence, not the horrific violence and destabilization wrought by the endless war on drugs.

Thanks to democracy, however, the victims of our disastrous policies in South America may elect leaders who want to kick us the hell out. I can’t say I blame them.
