I heard a while back that the U.S. estimates that Pakistan has approx. 200 nuke wareheads. They ramped up production, concerned about India.
All it would take is 3 or so set the U.S. back to a degree what would be hard to imagine. Even low-yield. Take out center of N.Y. city, L.A., Chicago, and maybe D.C. during a Joint Session.
Political, financial, social, etc. absolute turmoil. It would affect nearly everyone in the U.S., for years.
No mones from U.S. government to retired, disabled. No monies to the States. All banking totally disrupted. Probably Martial Law imposed.
Not something I want to see happen.
