I admit that it is possible to invade a country, overthrow its government, and occupy it indefinitely even after installing an independent government...
...and it somehow be construed as the invaded country's fault and just due. I just don't think Iraq falls into that catagory.
Regardless, even if we are there only for the purest and most moral reasons imaginable, there is a huge cost to us in money, lives, international respect, military capability, diplomatic effectiveness, etc. You always need to do a cost benefit analysis. Costs vs. benefits. Are we getting back as much as we are putting in? Are we getting back anything at all?
Jeez, I let you lure me in when I already told Tom I was too tired to respond to him. Sorry Tom.
