There’s really no way to be sure.
The problem is that one thing led to another to another. We supported Iraq in the Iran-Iraq war. (1980–1988). Iraq was our friend.
Until Saddam Hussein became our enemy.after he invaded Kuwait in 1990 – the US fought against him then. (and for Kuwait)
Then the US elected to attack Iraq after 9/11 even though Iraq hadn’t been the attacker – Al Qaeda and Afghanistan were. This was a war that was based on inaccurate intelligence had terrible planning.
So the US beat Iraq and the didn’t know what to do – US stupidity and lack of strategic planning led to the emergence of ISIS and the Islamic state. And thousands more needless deaths and billions of dollars spent.
All of this is a long way of saying that we- the US – screwed things up from the very beginning, and are paying for our stupidity 30 years later.
no. it has not been worth the American blood and treasure. The situation in Iraq is a testament of terrible American leadership from Reagan on forward.
