This is the person responsible for Ukrainians fighting Russians in a brother war.
Her name is Victoria Nuland and she is with the US state department operating in Ukraine. (You may remember her from trumps second impeachment attempt in which she testified for the prosecution.)
Well that wasn’t her first foray into king making. In 2014 she engineered a coup against Ukraine president yanukovich and was the one to hand choose Ukraine’s new President who would of course answer to NATO, but also got approval from then Vice President… Joe Biden.
She also admitted to ‘investing’ five billion dollars into ‘Ukrainian democracy’ making her and the USA the George Soros of Ukraine. So the person to blame is Victoria Nuland and the US state department.
