With words.
EU has also supported Ukraine with words recently.
I've seen ads on the telly making an emotional statement that "Ukraine is Europe".
Europe as a continent does not exist: it is a small corner of Asia. Eurocentricism needs to stop. This us-vs-them game needs to stop.
This invasion is terrible for normal people, Ukrainian (bombs), Russian (sanctions) and everyone else (instability, high prices). It could have been prevented if the "west"/NATO was not "pulling on" (arming) Ukraine. The NATO already have plenty places to make bases on Russian border.
See what happened to Cuba. The US/NATO also do not like bases on their border. They should have understood Russia also does not like that.
But then I believe NATO is more into the business of war then the business of peace.
