Tensions between Ukraine and Russia are at their highest in years, with a Russian troop build-up near the two nations’ borders spurring fears that Moscow could launch an invasion.
Ukraine has warned that Russia is trying to destabilize the country ahead of any planned military invasion. Western powers have repeatedly warned Russia against further aggressive moves against Ukraine.
The Kremlin denies it is planning to attack and argues that NATO support for Ukraine — including increased weapons supplies and military training — constitutes a growing threat on Russia’s western flank.
The picture is complicated — but here’s a breakdown of what we know.
The situation:
The United States and NATO have described the movements and concentrations of troops in and around Ukraine as “unusual.”
As many as 100,000 Russian troops have remained amassed at the Ukrainian border, despite warnings from US President Biden and European leaders of serious consequences should Putin move ahead with an invasion. And US intelligence findings in December estimated that Russia could begin a military offensive in Ukraine “as soon as early 2022.”
The history:
Tensions between Ukraine and Russia, both former Soviet states, escalated in late 2013 over a landmark political and trade deal with the European Union. After the pro-Russian then-President, Viktor Yanukovych, suspended the talks — reportedly under pressure from Moscow — weeks of protests in Kyiv erupted into violence.
Then, in March 2014, Russia annexed Crimea, an autonomous peninsula in southern Ukraine with strong Russian loyalties, on the pretext that it was defending its interests and those of Russian-speaking citizens.
NATO Secretary General Jens Stoltenberg has said “there will be a high price to pay for Russia” if it once again invades Ukraine, a NATO partner.
