That’s a good line to use on Putin.

Realistically, if Putin uses the nuclear codes, this is what happens:

A few warheads in Russia explode in their silos and the government blames the West. A bunch of other warheads are harmlessly shot down. A few actually find their targets and a few million people are wiped out. The west retaliates and suddenly the war is over.

BICS then becomes ascendant in global power, China claims Taiwan and the Philippines and possibly Japan, and Israel is wiped off the face of the earth as all sides turn it into a nuclear slag pile, killing Israelis, Palestinians and a large number of Lebanese and Syrians in the bargain.

Then things adjust to the new normal and economies rebuild, with the noted absence of Russia and Belarus.
