Ukraine and Russia face war. This is what's happening, and why
ABCThe chill of a Cold War hangs over Eastern Europe again, with Russian military manoeuvres and drills close to Ukraine, and the US warning a possible invasion could take place within days. "We can't pinpoint the day at this point, and we can't pinpoint the hour, but that is a very, very distinct possibility," US President Joe Biden's national security adviser, Jake Sullivan, said. "From here in the Black Sea region, all the way to the Baltic, allies are stepping up to reinforce NATO's presence at this critical time," NATO secretary-general Jens Stoltenberg said from Constanta. "We've made every possible effort to engage Russia, to look at the concerns that it's raised, to share concerns that we have, that European partners and allies have," he said.
