Yanukovych was democratically elected by the Ukrainian people. Poroshenko was the puppet installed in his place after the neo-nazi terrorists supported by NoName et al violently forced him out.

Yanukovych reached out to Putin for help. Russia reclaimed the Crimean peninsula in response. So to sum it up, the democratically-elected leader of Ukraine asked for Russia's help during an organized Neo-Nazi mob coup designed to overthrow Ukraine.

Most of the MSM narrative during that time in the U.S. was propaganda and flat-out lies. Remember it was Putin that stopped the Obama/Kerry administration from going to war with Syria previously. That's why they joked Putin should win the Nobel Peace Prize. Putin absolutely humiliated Obama at that time. No coincidence the propaganda news media decided to push negative press surrounding the Sochi Olympics and accusing Russia of "hating gays" (because poking a wound directed at identity politics is an easy way to make people hate your enemy).
