Just when the Obama administration showed signs of rethinking the disastrous "war on drugs" at home, Congress decided to export it big-time to Mexico. On foreign land, this monument to wrong-headed policy takes a particularly bloody and bellicose form.

A little-known measure buried in the U.S. 2009 Supplemental Bill would provide millions of dollars to corrupt Mexican security forces engaged in an unwinnable drug war. Disguised as a way of "helping" our beleaguered neighbor, the measure goes beyond even what the Bush administration planned. The aid package will push Mexico closer to a Colombia scenario and create a new quagmire to suck up scarce U.S. public resources.
