Russia's war in Ukraine has dramatically raised the odds of a direct confrontation with NATO due to Western sanctions against Moscow. Russia now considers NATO to be its enemy, and vice versa, former US Ambassador to NATO Ivo Daalder tells Ian Bremmer on GZERO World. In fact, Daalder explains, Russian military aggression is a very real and present danger.

That makes the current situation in some ways even worse than during the Cold War, when the United States and Soviet Union tried to find ways to coexist and set up arms control agreements.
