You're right about points 2 and 3, but I'm not so sure about point 1.
I don't know if you realize what's going on in Europe. This week, German politicians are publicly telling journalists that there should be a missile strike against the Kremlin or the Russian Ministry of Defense, i.e. to obliterate these buildings and their contents.
What will the response be, regardless of whether Putin then flies over the Jordan with a few hundred military personnel? the response will come back automatically and probably nuclear. Whether it's big nuclear weapons or small ones, it doesn't matter, it could trigger the Russian system dead hand.
The Germans want a strike against Russia, the French and the British anyway.
Always expect Europe to try to drag the USA into this ****, at the moment it's really possible.
Then the third piece of the puzzle comes to light: whoever is crazy enough to launch a nuclear strike is sitting on your floor and his name is Joe Biden.
We are surrounded by idiots and the danger of a nuclear strike has never been higher. Honestly, if it happens nearby I don't want to survive it either, but since I'm surrounded by mountains and my neighborhood is of no use to Uncle Vlad I might get lucky, but in the long run living in the stone age sure isn't fun and you don't get old.
