Europe couldn't even stop Little Russia (Serbia) from genociding Bonsian Muslims and Kosovo-Albanians until the US-led NATO intervention had to put a stop to it twice.
Also Norway can replace a lot of the Russian gas supplies.

If your justification of NATO is their entirely illigetimate and overall worthless intervention in Kosovo, I don't think we will ever see eye to eye. The bombings were highly destructive and didn't solve anything. The war stopped when Russia urged Milošević to surrender after a lot of diplomatic negotiations.
