Ukrainians have every right to “interfere” and “influence” the government of Ukraine. They deposed a corrupt regime that was pro-Russia and Russia invaded
Politically Nato and US pushed for new elections quickly and had Poroshenko lined up months before. There's a boatload of evidence which shows and proves as much.
The difficulty is the US put pressure on countries dipping into the US Gov. to support Poroshenko...and a host of other strong arming....which is usual when a nations leader is disposed by a coup.
It doesn't matter now what it was...Poroshenko is in office...anymore than the fact Crimea is now Russia's. They all acted quickly in the time frame they had to accomplish what they wanted.....
What they couldn't guage was the response of the Eastern Population to resist the new Kiev Gov...and it went form there.
