Russia-Ukraine standoff: What you need to know now
CBSN
Russia has massed well over 100,000 troops near its own border with Ukraine and in neighboring Belarus, leaving the country surrounded on three sides. The buildup and position of those forces has drawn warnings from the White House that Russian President Vladimir Putin could order an attack "any time," and may well do so before the end of this week.
The U.S. has poured military hardware into Ukraine and contributed to a buildup of NATO forces in Eastern Europe in response. Russia and NATO are both carrying out military exercises in the region and demanding that the other party step back first from the brink of war.
Along with European partners and the G7, the U.S. has warned that any Russian invasion of Ukraine would bring "swift and severe costs" for Moscow, in the form of sanctions.
