He is the top advisor to the President of Ukraine.
At the most charitable interpretation, you would say he is the modern day Nostradamus; with the ability to see the future.
At worst, you would conclude he was going to sacrifice Ukrainian (the price to pay), so they could join the Nato club. In his words "Of course, a big war with Russia and becoming part of Nato as a result of winning against Russia". And he said this in 2019.
Wondered if he ever let the people of Ukraine know they were about to become sacrificial lambs?!?
