WE, the USA started it, by running a coup in 2014. An insurrection where the legally elected leader and his cabinet had to flee the country. WE DID THAT.... that was the First Strike
Sorry, but it started when Putin put pressure on Yanukovych to betray his electoral mandate and renege on the Ukaraine-EU agreement, and attempted to bind Ukraine to Russia through the Eurasian Economic Union. The protests were a popular reaction. The agreement had already been approved by the parliament as was support by an overwhelming majority of the population. The protests became violent after Yanukovych set his security forces upon the protesters. Popular opinion turned against him and he fled the country. The democratically elected parliament then declared that he had abandoned his office. This was not a CIA led coup. Enough with the Russian propaganda.
