Russia invaded and annexed the Cremean Peninsula in 2014. It was anti-government demonstration occurred in 2013 that triggered Russia's military action two years ago. That demonstration, however, overthrew pro-Russian administration and led to pro-Europe & American government. It was Mr. Biden, then Vice President of Obama administration, that supported strongely the anti-government activity. In fact, he took charge of Ukraine problems at that time. Therefore, he should be more accountable for his actions and remarks than other leaders.
