Ukraine is not even in NATO.
US troops were there to protect NATO countries in case of Soviet attack.
The Soviet Union doesn't even exist anymore.
AND, US troops were not sent there to use nuclear weapons on Russian civilians.
The Russians will be very happy to return serve if America did that.
Russia is not Japan.
Russia is far bigger and they have the biggest and most powerful nuclear arsenal on the planet.

This is 2022, NATO exists to protect against Russia, and currently, Russia has started the biggest European war since they started invading nations at the beginning of WWII, such as Poland and Finland.

Russia is why our troops have nuclear weapons in Europe.
