They're handling Ukraine better than America is "handling" Iran

I honestly don't even understand what you mean by that. Europe has accepted an extraordinary number of refugees from Ukraine giving them immediate and full rights to live and work within its territory, keeps donating billions of dollars worth of goods to keep Ukraine going, provides training to Ukrainian military personal and ramped up its military production specifically to bolster Ukraine.

How has Europe failed here? Did you expect Poland to start shooting missiles towards Moscow, or something else?
