After Russia started the verbal food fight in New York Jan. 31, the United Nations Security Council isn’t going to help Ukraine. But NATO still can, I say in my Feb. 1 piece for Fox News Opinion. It's sad to see the UN sidelined by Russia and China. Article 51 does give Ukraine the right to self-defense and allies can help. Yes, NATO is reluctant, but remember NATO won its 1999 war against Serbia with a precise, 78-day air campaign using no ground troops. I doubt NATO will stand by if Putin unleashes horrors in Ukraine.
