Am so glad that it will be our politicians that will go to North Korea and fight for us. Thankfully they will take the bulk of DC with them as back up. Keep me posted as to how this works out for them. Goodbye swamp....
This sounds wry, but I am unsure what you mean.
Donald Trump is commander in chief, and the state of war with North Korea was never, ever called off by Congress. It is the Congress of long ago that set this into motion.
But as for an ICBM at DC... this is the reason we have SDI. (Hail the memory of Saint Ronald Raygun.) A Russia sized or China sized attack would be harder to totally thwart if possible at all, but this is onesy-twosy stuff. Not really worried here.
