The other countries are going to want peace and will be happy to accommodate Russia in order to let them get on with what's important while having choice sound bites about standing tough.
All they're waiting for is public opinion to stop be so riled up. That's why you hear "yes, send planes. Wait, no. Okay, we're thinking about it. But this is why we can't." Or Patriot missiles--it was a yes, then no, then they're thinking about it. They were going to let S-300s get sent--don't know if they have been sent, but a couple days after "they'll be sent" they were "in discussions as to how to make it possible". Missiles for the S-300, sure. Anti-ship missiles? Well, yes, they need those. Wait, do they have the facilities for firing them?
Nothing that would give an actual reasonable offensive operation is sent. At best the Ukr forces can tweak the front lines unless they can get behind the Russians, knock out their support, and force a retreat not through battle but by making them see they'd be attrited to death.
What they need is the firepower to break through and retake all of Donechchina and Luhanshchina. .
