War with Mexico?

Atrios describes the Mexican-American War of 2006:

. . . I know what they're thinking at the White House. We can have a lovely little 'fake war' at the border, one with all the cool uniforms, hummers, helicopters, etc... A war which is entirely safe. A war where there isn't really an enemy. And the president can safely visit that war, prance around in his codpiece, yell things out a bullhorn while sitting astride a massive hummer. Ridiculous, but that's probably the plan.
