In my humble opinion, until our learned scientists, respected engineers and inventors come up with some device or method to detect hidden explosive devices in places like Iraq - perhaps its best to cordon off the entire country, come up with appropriate sanctions, patrol the peripheral area and keep our soldiers out of harms way. There are no doubt some countries are hell-bent on bringing the U.S and Canadian economies to our knees. I say - go after those who supply the components for these devices. In the interim, utilize aerial reconnaisance, and robotic looking artificial soldiers....wherever possible...
