Deter Russia? Is he insane? 3,500 U.S. nuclear warheads didn’t “deter” the USSR from invading Afghanistan. The threat of sanctions didn’t deter Putin from grabbing Crimea. If Democrats and McLame-Linda want to push a Jimmy Carter foreign policy, Trump will laugh them off.
The US had 20,000 nuke warheads in that era.
9,000 of them on intercontinental delivery systems.
