Russia's Invasion of Ukraine Is a Warning to the United States

CBS News' Charlie Daggeta was in Ukraine one year ago when Russia launched the largest ground invasion since World War II.

CBS's David Martin is at the Pentagon, where a recent war game showed the U.S would run out of a key weapon while trying to stop a Chinese invasion of Taiwan. We're seeing firsthand how the Navy is preparing for that possible conflict in the Western Pacific.
