Ukrainians are the ones who are most against "diplomacy". We've been through this before. Russia has broken a long list of "peaces" every time using them as an opportunity to rearm and take more next time. There is nothing that Russia could do or promise.

Orban is a scumbag who is working to give the Russian military time to invade Ukraine again. He is a deeply evil person who is doing what he is doing because he's hoping to get his own piece of Ukraine (he's making claims that part of Ukraine ate rightfully Hungarian territory).

Negotiating with Russia is as absurd as negotiating with Nazi Germany. Exterminate them with force.
