The US
Are you ready to put billions of dollars in aid to Ukraine in the next three to five years? And not like most of the money goes to American military complect but to put this money into Ukirnian? If not stop talking about peace because now the peace will be on Putin's terms, you can talk about peace only after Ukraine takes Krym.
To this end, they need rockest and planes and of course, they need to mobilize more men.
If Russia comes on top of that war it will be only the first stage of their aggressive policy. You can't hide from that.
Also, stop with that EU delusions, seems to me you as many Americans have this abstract view of the EU as something akin to the US, it is not anything like that and looks like it going to crumble or split or will remain half dead.
Also without NATO i.e. America in Europe only a few countries that have a vital interest in opposing Russia its Finland Sweden, Poland, and the Baltic states, all the rest of them are ( Ukraine as well but that is a diffent issue) OK with Russia and some are pro-Russia as you wouldn't belibe namly Germany and France.
So Trump mocking Germany and saying that should be attacked by Russia is wild because if anything Germany would make a deal with Russia in a heartbeat and so goes for Russia.
You need to understand the dynamics in Europe to have some notion of what you are talking about.
I don't get why American posters here have this rooted conviction that everybody in Europe just loves to have an American overlord and NATO and the US military presence.
Germnya and Frwacn positively hate it and would have you kicked out ages ago if they could. So wake up will you?
The only countries that years for that presence are those on the front line of NATO bordering with /Russia.
