I am torn on the issue of U.S. involvement anywhere, it's a "damned if you do & damned if you don't" situation no matter what that situation is a huge part of the world thinks we're wrong for doing whatever we did, even if what we did was nothing.
No one is perfect, that goes for individual people & govts. But,(there's always a but) I'm for winning at all costs & if you can't win then at least throw the last punch. Sort of like that star trek movie the wrath of kahn, "With my last breath, I spit at thee; For hate's sake, I stab at thee" that was a Captain Ahab quote from moby dick too so I don't feel so bad.
I think I'm tired of being on this over-crowded mud ball & I'm tired of the world wanting us to help them when they need us & then wish us dead when it's the in thing to do. Even though I feel that way, I don't think we should be the first to sling an atomic weapon at anyone. Every other weapon at our disposal should be used first unless we are attacked with an atomic weapon first.
If I were in charge of the arsenal, you can bet I'd push the button without hesitation if the need arose...but I think fuel air devices will do fine up until then. So - NAY.
Edit: Quote,"If we use it, surely they will use it as a terrorist attack inside the US."
Answer, if they had it, they'd use it, whether we did or not. They want all of us dead, men, women & children & our pets & our buildings destroyed. They want us gone from this earth completely.
