If Russia attacks a NATO country (like Poland) then that will be a thousand fold increase in escalation. All the air power from the USA will be brought into the theater. It will eventually escalate to bombing Moscow itself, and retaliation in bombings in Washington DC. An ALL-OUT WORLD WAR III!
It will be the end of everything and Klaus Schwab, George Soros, Bill Gates will emerge from their palatial bunker to see a world in ruins. They will proclaim, Mission Accomplished!
Russia may be forced to reach the conclusion their best option for survival would be to engage itself in a massive* first
strike.
