The reason is the same as why it is more profitable to support a neighbor who is fighting off robbers, rather than robbers who are planning to come to you later.

I think that robbers in USrain are problem and their friends in Europe are problem. Neighbours are welcomed to sort problems.
Russia is a robber it invaded Ukraine in 2014 killing people and annexed Crimea. No neighbour supported Ukraine, then Russia move full scale invasion of Ukraine in 2022 killing thousands of cillvilian Ukrainians, stealing children and wiping cities off.
Sorry if you're not aware about it. Make your own research.

Umm, I wouldn't use the leftist millennial dictionary to spell USraine!
