The same way anyone starts negotiating with anyone: open a dialogue and exchange demands, and then work to make concessions and compromises. They won’t do that, though, because then the infinite money spigot from the US will shut off because America doesn’t want this war to ever end.

You tell me where you live, I'll break into your house and steal half your stuff.

Instead of fighting back or calling the police, we can negotiate so I can have half your stuff. Sound good?

I dunno, do you have nuclear weapons that could cause the apocalypse?

Countries aren’t people. The scale the work on is much greater.

You’ve got an important word there. Scale.

Countries aren’t people but they’re made up of them. It wouldn’t take nuclear weapons to annihilate your household.

Russia has invaded Ukraine’s home and tried to lay claim. Now you’re suggesting they give up what was taken from them to satisfy your desire for peace.

The analogy the other person used is fair. In another analogy Russia is nothing more than a bully. We’ve long moved past the time where the advice we give is to just give the bully your money so they don’t beat you up and take it anyway.
