No nation openly agrees to let us use their territory to attack another nation. Such action is an act of war and always requires an individual decision at the time. Iraq doesn’t exist to be used by us to attack Iran. That does not make them “ungrateful” They didn’t exactly ask us to invade them whether it brought them some good things or not.
Howdy! Long time, pal. Must be an election comin’ up ............. FRegards
