Is your opposition mainly due to the religious reasons? We can invade Islamic countries but not Christian ones?
We shoudln't invade ANY country without a darned good reason. Invading Afghanistan (Islamic) made sense--getting rid of the Taliban and al-Quaeda's infrastructure. Invading Grenada (marxist-leninist)made sense--eliminating a communist outpost on our doorstep. Attacking (we didn't really invade) Serbia was cowardly and pointless; it was no threat to the USA or its interests AT ALL. A waste of treasure and (mostly Yugoslav) lives.
