William Cooper11 said:Ukraine wouldn't even be in this position if the West hadn't started sending military aid. We’ll just have to wait and see how this plays out. Personally, I could see a Western military intervention involving maybe 100,000 to 150,000 troops—a coalition of the Baltic states, Poland, Finland, the UK, the Czech Republic, and Slovakia—backed by US air power. That should be more than enough to push Russian forces out of Ukraine, though Crimea might stay out of reach.
Relying on air power is a double-edged sword. The Russians would simply strike back from Belarusian or Russian territory. That essentially mandates the immediate neutralization of those launch sites, which constitutes an attack on the Russian Federation itself. Once you cross that line, you're effectively opening the door to World War III; neutralizing those systems happens the moment their positions are compromised.
If an intervention were to occur, it absolutely must include Crimea. Crimea has become a matter of principle, and there is no room for compromise there. Giving in to the aggressor regarding Crimea today is nothing more than an invitation for Russia to launch the next conflict once they recover and regroup. That is precisely what we are trying to prevent through preemptive action. If we fail to stop them now, we might as well give up entirely.
