The idea that NATOs expansion poses a threat to Russia is ridiculous. NATO does not even encompass the entirety of Western Europe. If Russia is worried about NATO invading them, should Sweden, Finland, Ireland, Switzerland and Austria be worried too?
Should Sweden and Finland join an alliance to invade Norway, under a paranoid delusion that NATO are going to invade and try to take over both countries? It's ridiculous.
This is nothing but a power grab by Russia and them flexing their power. It's totally abhorrent.
