Public support for sending US troops to Iraq would be around 10 or 20%.
McCain, Grahamnesty, Bill Kristol, probably Cheney, ....only the neo-con club wants to go through that again.
I think you badly overestimate the popularity of sending in troops.
If I recall correctly it was the Bush presidencies that took the USA into the hell hole of the middle east in the first place. The first time was to save the Saudi kingdom to back stab the USA once again for oil revenues and the second time was to avenge what wasn’t done the first time. Shame on the USA ‘leaders’ who wasted the lives of USA young men to keep foreign oil flowing. I feel entitled to make such comments as a survivor as an infantry person of WWII who had his only sibling brother killed on Okinawa. We knew what we were fighting for was worth more than Saudi oil which was going to the Nazis.
