Recipe for disaster: One 50 gallon drum, one 500 pound bomb, 1/2 cubic yard of low enriched Uranium. Fill the drum 1/3 of the way full w/ the low enriched Uranium, add the 500 pound dumb bomb, fill rest of drum. Transport to Mexico via cargo ship, bring across border into US, transport to the city of your choice and detonate upwind on a windy day. Remember, these are the same people who cleared mine fields by running 10 year old boys through them with the promise of martyrdom. They are playing a very dangerous game and will likely pull Russia into the middle of what ever they end up in. What ever it is, it isn't going to be pretty.
