Time is on the side of the defender. They have fought "mighty" Russia to a standstill and are comfortably holding the frontlines. Remember, in the last 2 years, Russia has not made any significant advancements despite throwing everything they have into the effort. Their casualty numbers remain atrocious. They are weaker and more vulnerable than they've ever been. They can't even take back the large chunk of Kursk that Ukraine occupied last summer. There's never been a more golden opportunity to finish this vile enemy off than now.
If I were president of the US, I wouldn't even consider talking to Russia. I wouldn't even respond to them if they reached out. The first thing I'd do is send Ukraine 200-300 F-16's, 1000 tanks, and another 6-8 Patriot air defense systems. And that would just be the start.
That's how you properly deal with an aggressive terrorist state that's been a thorn in the side of the West for 100 years. Time to end the game.
