Good. Now also please give them the needed financial support

My question is why is the US rejecting anything, isn't that a war between Russia and Ukraine?

There's no negotiation needed. Russia moving out of Ukraine and paying for all damage until everything is pre crimea. If that is all done, rebuild and paid for, then, they can negotiate for less punishment on top. That's the kind of negotiation you start because both sides have something to gain and not one to keep his unjustified war territory.

Why hasn't the cancer killed the mother fucker already?
