Wow Obama is off his rocker, even Bush isn't this dumb. Pakistan is nuclear and has 8 times the population of Afghanistan or Iraq, not to mention they are at least an ally to us (albeit a not very effective one).
"Democratic presidential candidate Barack Obama said Wednesday that
he would possibly send troops into Pakistan to hunt down terrorists, an attempt to show strength when his chief rival has described his foreign policy skills as naive.
The Illinois senator warned Pakistani President Gen. Pervez Musharraf that he must do more to shut down terrorist operations in his country and evict foreign fighters under an Obama presidency, or
Pakistan will risk a U.S. troop invasion."

I actually think Obama is probably right about Pakistan having some terrorists hiding there, but the country is somewhat of an ally, has a huge population and is NUCLEAR. Sorry it would be insane to invade them, Obama is nuts.
