OP you forgot to quote the statement from Mr. President, thus I do not get what to analyze and give feedback whether its right or wrong. However, I believe Ukraine suffered the most lost compared to Russia, personally I will totally disagree to Ukraine yielding their territory to Russia for that flimsy of a reason. Ukraine has suffered a lot, she must keep her territory and also be compensated.
Sorry my bad I forgot to drop the twitter link to the post
here you can watch the video for yourself so you can get the proper words of the president.
