The US and Europe has no choice but to support Ukraine, because giving in to nuclear blackmail is not an option. The russian nuclear threat at the beginning of the war, at a time when Putin thought this would be over in a couple of weeks, is now the reason Russia is destined to lose the war - no matter how many photo shoots Putin is making at weapons factories.The Russians are ready to incrementally fight up to nuclear war and the US and Europeans know. That's why the "allies" are providing limited support to Ukraine and are just profiting as much as they can until truce is agreed and Ukraine meets Russia's demands. Russia has switched to war time economy which means it has increased manufacturing of weapons and the number of men under training. Time is not on Ukraine's side. Meanwhile the war will remain bloody with fear and hatred propaganda fueling the war and the UN spectating on the sidelines.
