Cong. Adam Kinzinger says if Russia invades Ukraine, it will become the biggest military conflict in Europe since World War II. He says Ukraine is more ready to fight the Russians than it was when Russia invaded Crimea. Russian leader Vladimir Putin says he wants to keep Ukraine from joining NATO. Kinzinger says Putin wants to take Ukraine as part of a plan to rebuild the Soviet Union.

Kinzinger says if there is an invasion, the U.S. should put crippling economic sanctions on Russia and not just a slap on the wrist.
