Is that something trump is saying or is that an actual fact? It's hard to tell the difference these days ... And from my stupid European mind this is not at all how things happened.

Also the conflict still didn't stop, I don't see how America is somehow more capable of doing something when they didn't do anything?

I'd say it's more unwilling. Until the will is there, we'll never know if they're incapable.

Europe's forces could probably end it in a day, I would suspect. The problem is everyone is unsure of how unstable Putin is and how he would react to several dozen bombers and cruise missiles flattening all the unfortunate Russian soldiers on the wrong side of the border.
