One big difference between Hungary and the US are guns. It’ll either can lead to a revolution much easier than in Hungary, or a Krystalnacht that is followed by the return of KKK-style lynchings.
For Ukraine, peace is not a real option. They can choose between war and being oppressed by Putin. And now, how they want to go out in history: in a war with glory, or under Putin’s boot who tells them: “no, you’re Russians, speak Russian”. I refuse to call “ethnic cleansing” peace. At best, it’s just the illlusion of such, because tanks are not crossing state borders.
Fascists like Trump choose their henchman based on loyalty, not skills. He will just get a lot of badly trained soldiers as basically meat shields.
Not only that, but “peace“ deal with Putin will only benefit Putin, as it will give him time to regroup and improve his strategy, while the military aid to Ukraine stops. Then he’ll say: “oh shit! Ukraine is attacking us again! They broke the peace deal” and continue the invasion.
