Yes, the middle east would have been perfectly fine, without American intervention
No, the middle east would have been just as violent, or even worse.
Generally I think the war would have put villages,etc in danger and they would have have to eat small amounts of food, etc, but maybe if the Americans didn't come they would have lived peacefully.
Without all of the invasions into middle eastern nations like Iraq the middle east would have far less terrorists to deal with.
All we need to do is fry the place so hard the worms choke on the dust. There, it's definitely peaceful now.
Other than maybe Iran, I say it wouldn't have made a difference
That part of the world was on fire long before we got there.
We really dont know, It could be more peaceful or more violent.
The region has been a battleground for thousands of years and it's not like the Shiites and Sunnis would love each other if America never intervened, they've quarreled since Muhammad died. Maybe the sand and heat makes people grumpy.
