What I read is that Russia might have 2 maybe 3 years max before they are completely exhausted for tanks. War has already gone 2 years. It's very reasonable to think that if the US funded Ukraine for just 2 more years, Russia would have no ground capabilities and therefore a severely limited ability to keep the war going. So the talk that Ukraine can't push Russia out holds less water than some think.
If this goes on another 2 years, their could be a million dead.
That's a lot of dead bodies.
