But yes, it's possible that NATO forces could enter the fight. There are already large quantities of NATO troops in Poland, Estonia, etc. Entire US, British, French, etc. brigades on standby.
This isn't new -- we've played these games for damn near 50 years of Cold War. Most of the leaders of NATO, to include Putin and Biden, were Cold Warriors and grew up during that era. They know the game and what's at stake.
But that means lots of staredowns, not necessarily a lot of fighting. Ukraine isn't NATO -- hell, 50 years ago UKR was USSR, and would have been shooting at NATO forces -- and if they need to be sacrificed to collapse the Russian government then so be it. Welcome to Realpolitik.
To that end NATO will prop them up as much as needed to continue grinding down Russian military and economic forces. I believe they will let UKR collapse and be taken over instead of sending troops; only if NATO forces are attacked directly, or maybe if nukes are involved, will NATO do anything more than it is now. Furthermore, it's possible that Ukraine actually wins -- they appear to be absorbing, at high cost mind you, the renewed Russian offensive, and may soon be able to hit back with their own...
at the same time a narative is being developed in all the major media that the freedom of europe and west depends on ukranian victory. if thats the case, whats the next logical conclusion if ukraine actually begins to lose the war? to me this smells of preparation of the general population for a (much) larger war
We are very far from average Joe being sent to the Russian front. Partly because there is a professional army that will be involved before that, but more likely it will not, in order to avoid nuclear conflict. I think you should worry more about that than the general population being sent to Ukraine.
The alternative is that we are afraid, we do nothing, and once Putin finishes off with Ukraine, he is ready to invade the ex-Eastern bloc countries, and then go further West. Because if everybody is afraid, who is going to stop him?
