Assume you play game of chicken with Putin. Two cars heading towards each other, the one who swerves loses. Putin throws out the steering wheel and cuts the breaks, put on headphones and a mask. What do you do? Copy him? No you swerve.
If we do nuclear WW3 we all die...
So if Putin start the process of it, should we just play along and die or do we surrender? Let's be honest, we are not as irrational as Putin and would lose the game of chicken. Sucks to admit it, but that's the truth.
West would give Ukraine to Russia, let Russia do whatever they want until they touch NATO. That is the line hill we decided to die on, and that's likely what we would do...
