A highly rational argument. Alas, democracy ensures we don't elect highly rational people because the masses prefer clowns and imbeciles. Biden has done precisely the wrong thing every step of the way and will continue to do so until the orange vermin Trump waddles back into the White House on 20th January 2025 and thereafter does everything possible to hand Ukraine to Putin. Moreover, a sort of nuclear strategic balance was possible when two players existed (the West, e.g. the USA, and the Soviet Union) but with multiple players (China, NK, etc.) balance becomes impossible and miscalculation becomes inevitable.
