“Most if not all first world nations are capable of nuclear weapons and launch systems. “
Really? Mind naming the missile each has that can loft a nuke into our upper atmosphere? Go ahead, take a few days. Google until your hearts content. We’ll wait.
The list is quite extensive, but for your amusement I will simply point out that Iran for instanced launched a satellite into space just the other day. Something in the order of a few hundred lbs. I’d say Iran is well on it’s way to being able to launch an EMP attack on the USA using such a missile from a large ship off our coast.
