How about a clear term of engagement, goal, resolution? I don't think we'd respond too well for France sending troops regarding Mexican citizens inside U.S. borders. We are not engaging state actors in foreign nations, and we are not engaging foreign actors within our own borders.
As it stands we have far more military engagements on foreign soil than we've seen since and maybe including WW2. We have a corrupt political system and state that is in ever excessive violation of our own constitution, and a people oppressed and divided.
We really need another JFK or Reagan in terms of charisma and general popular support, if not in somewhat similar political views. Another Truman or Eisenhower would probably be better, but could never get into office today.
