The United States has spent over $1 trillion promoting democracy in far-flung Iraq and Afghanistan while friendly neighbor Mexico gets a fraction of that in its prohibitionist fight against drug trafficking organizations. Mexico's frustration with Washington's priorities has plunged ties between the two allies to their lowest ebb in years. Last year alone, the U.S.-backed campaign claimed the lives of over 15,000 people in Mexico -- that is more than double the combined civilian deaths reported in Afghanistan and Iraq, where the United States has spent over $1.2 trillion in the past decade.
