Even if Russia were to occupy Ukraine entirely they'd still lose in the end. They don't have the resources to successfully occupy a country of Ukraine's size and population if Ukrainians actively resist. Putin's plan depended on a quick installation of a puppet government and there being little to no resistance from the Ukrainian population. That didn't happen, Russia will ultimately lose. Whether they lose after a few years of a conventional military war or loses after decades of Ukraine conducting an asynchronous warfare campaign against an occupation, all paths lead to a Russian defeat.

Holding a country is significantly more difficult to achieve than invading a country. Russia hasn't even been successful in invading Ukraine, they haven't even gotten to the hard part yet.

So the idea that not supporting Ukraine will somehow lead to a faster resolution to the war is simply bullshit propaganda. The only way to end the war sooner is to expedite a Ukrainian victory. Anything else is promoting Russian occupation and very likely another Holodomor kind of situation.

Do you want another Holodomor?
