Russia Is Beefing Up Its Air Defenses, Top U.S. Air Force General Says
Here are a few different ways to look at Russia. You can see some of the grandiose moves they've made on the world stage. Several months ago, Russia began a military intervention into Syria. This came after Russia's hostile takeover of Crimea, territory belonging to Ukraine. That prompted a strong warning from President Obama at the U.N. General Assembly last September.
...But it is also worth watching what Russia is doing more quietly. For one thing, U.S. military officials say Russia has been building up a complex missile defense in Kaliningrad, the Russian enclave between Poland and Lithuania. This has General Frank Gorenc worried. He's the commander of the U.S. Air Force in Europe and Africa, and I asked him what Russia's military looks like right now.
