Haiti has been a powder keg and had so many inbred political issues that the U.S. has sent the military since BEFORE we entered World War I.
Many a Marine legend received a Medal of Honor or Navy Cross for actions there. Chesty Puller, Dan Daly, Smedley Butler, and others.
I feel for the people of Haiti. I have known and been friends with many. Wonderful people, but what the political elite in that country have done to it, and the people is abhorrent.
