You must not be counting the recruiters of the US military, one of histories biggest killers of innocent civilians, and still killing today, as we speak.
It wasn't a war to spread Christianity or a war against Islam.
In the first Gulf War we were fighting to kick the Iraqis out of Kuwait. The Muslims in Kuwait were very grateful.
In Afghanistan we were allied with the Northern Alliance against taliban, who were very grateful and very Muslim.
In Iraq we really screwed up, but we overthrew Saddam's regime , and the Shiites were very grateful when we set up a Shiite government.
The streets were filled with crowds of cheering Iraqis when Saddam Hussein was dethroned.
If Sadaam hadn't been such a sociopathic terrorist, tyrant, and commited so many crimes against humanity, America would have never been over there in the first place.
Now, the war in Syria has to do with Dick Assad terrorizing his own people, and his enemies doing the same thing.
We are allied with Iraqis, Iranians, and other Islamic countries in the fight against Isis, so to identify it as some sort of a Christian Crusade against Islam would be asinine ,
since we're actually helping a lot of Muslims who want our help and I've seen them begging for more American military support.
