“I doubt that illegal aliens are strong enough to carry a Nuke across the border.”
Nah, that’s not much of a danger. “Suitcase” nukes do exists but it’s not very likely any terrorist gets their hands on one unless it’s an attack sponsored by one of our biggest enemies, in which case they would be better served by just declaring war and hitting us with a real sneak attack, since we would quickly know who was responsible.
I think there is a lot of non-nuclear support that Russia could give a terrorist organization. I do worry that eventually Russia will feel that turnabout is fair play, arm our enemies, and push them to act on American soil.
With the border open and the three letter jackboots focused on persecuting traditional Americans what is to stop it?
