1. Yes, invading Iran instead of Iraq would have been harder and costlier in lives and money and we would have had to do it entirely without the support of any other country. Britain and Australia would not have supported a unilateral action against Iran at the time. There were strategic military reasons for doing Iraq first, not the least being that we were fairly certain no other muslim country would also declare open war against us to help him. That is not what would have happened if we had invade Iran instead of Iraq, we very likely would have instantly faced a very united opposing coalition of Arab nations.
2. Technically the failure to abide by the ceasefire terms from Desert Storm was the provocation and another declaration or provoking act was unnecessary.
3. Declare multiple wars on multiple fronts? LOL, yeah, that's feasible. I prefer a WOT with the identified Axis of Evil.
4. Human history is generally a chronic state of war with an occasional peace breaking out. Get used to it, the cold war is over and it's now lukewarm. The time for total war is not yet, and may even be avoided if eurotrash pull their heads out of their keesters in time. I don't know that the US will pull their nuts out of the fire this go round.
I do not call people who openly support taking out Iran's nuclear program chickenhawks. I was referring to those who secretly hope someone (Bush or Israel) will do it, but do not openly support the action. These are the same people who will vetch that Bush did nothing or will recoil in horror at his gunslinger mentality if he does. You know the type, they want something "done" without having to take responsibility for it, typical leftist magical thinking. You just can't win with these creatures of the welfare state.
Also you seem to forget that the WOT has electronic and monetary fronts that naturally are kept out of the press as much as possible. Iraq is a just one battle, one move on the chessboard that keeps the focus and the energy of the enemy over there and not over here.
Every soldier wounded or killed over there is personally protecting me and my family from harm and I remember that always.
