Absolutely. Russia is not interested in invading any country but if it threatened with NATO then we will absolutely invade and beat the crap out of you if necessary. And No, Finland does not count. Same with Baltic States.
Ukraine in NATO is absolutely a threat, Kazakhastan too. Georgia, Armenia. In short, Former USSR republics out of NATO and that's final.
NATO is a criminal organization which should be disbanded with people going to prisons. But as long as they stay where they are, that can wait.
