Some Iraqis may have very well wished for the U.S. to remove Saddam Hussein from power. That has no bearing on the misrepresentation of the intelligence by the Bush administration in order manipulate the country into going to war. It also has no bearing on the bungling ineptitude of the Bush administration in prosecuting that war and the subsequent occupation of Iraq.
Read Cobra II. It's a very balanced account of the planning and prosecution of the war. Rumsfeld micromanaged the military, and unfortunately for everyone involved he was grossly incompetent.
"Almost 1000 soldiers died!"
What about the Iraqis that just up above you claimed we were trying to save? Over 200,000 dead documented by Iraq Body Count. These deaths are all a result of the invasion of Iraq and the power vacuum which ensued.
"you learn from the mistakes and move on"
The U.S. borrowed the money to pay for the war. The final tab will be in the trillions.
Tens of thousands of American lives have been shattered, hundreds of thousands of Iraqi lives have been shattered, millions of Iraqis have had to flee their homes, barbaric ISIS has taken over parts of the region that the Bush administration intentionally weakened. Iran has turned into a major player in the region. The war was a complete, unmitigated strategic disaster.
