Over 10 years while fighting in Afghanistan Russia lost 15,000 troops which helped cause Bankruptcy and end of Soviet Union in 1991

It wasn't just the loss of 15,000 troops over 10 years it was also stinger missiles supplied by American CIA to Mujahideen like Osama Bin Laden's group that defeated the Soviets in Afghanistan. Millions and millions of dollars of Tanks and helicopters and planes were destroyed by shoulder fired missiles supplied to the Mujahideen by U.S. through CIA which defeated the Soviets in Afghanistan. So now, losing 15,000 soldiers in one month to the Ukrainian Army from Stinger missiles and Javelin Anti-tank missiles which are shoulder fired weapons accurate at a distance and heat seeking missiles is causing possibly another banktruptcy in one month rather than over 10 years like before in Russia. When you combine this with Sanctions put upon Russia now by the whole western World this could cause Putin to be removed from power or another bankruptcy in Russia (either one or both).

Because Putin has nuclear weapons we need to understand that if he is boxed into a corner that he would use these nuclear weapons on the rest of the world "BEFORE" he was driven from power by his people.

This is only realistic to assume this from Putin.

History in a sense is repeating itself only quicker this time because the whole western world is now against Putin. So, instead of losing 15,000 troops in 10 years he might have already lost 15,000 troops in 1 month because of government corruption and not training draftees before the young men were sent into battle with no training at all. (like lambs to the slaughter unfortunately for them). They weren't even told where they were going and only told that this was a training exercise! (because they had no training at all because the oligarchs siphoned off the money for their training into their own super yachts already!
