Biden: Battle for Ukraine Will 'Not Be Won in Months'

President Joe Biden on Saturday called for Russian leader Vladimir Putin’s removal.

Biden also used a speech in Poland's capital to make a vociferous defense of liberal democracy and the NATO military alliance, while also saying Europe must steel itself for a long fight against Russian aggression.

In what was billed by the White House as a major address, Biden spoke in front of the Royal Castle, one of Warsaw's notable landmarks that was badly damaged during War II.
