Vladimir Putin has positioned more than 100,000 of Russia's troops and tanks on Ukraine’s border. US President Joe Biden and Nato allies say Russia could be about to invade Ukraine - an independent European nation.
Putin says he’s protecting his people, and it’s the West who are pushing for a war. Neither side are backing down and weapons from Nato allies are flooding into Ukraine to counter the Russian threat.
But this conflict has been decades in the making. It's not just about the threat of invasion now, it’s about history, it’s about geo-politics, and it's also about Putin himself.
