Unfortunately, Russia has achieved its intentions and attacked Ukraine, I really thought that would not happen - but unfortunately, no one stood behind Ukraine firmly and with attitude. It all reminds me of 1991 and how the world stood aside when similar beasts invaded my country and committed the greatest crimes against humanity since World War II.
It is bad because this approach of Putin and Russia under his regime will put a world into a new era which I believe most of us don't want to see.
Big nations can send their armies to other nations and try to re-draw borderlines if they want. China might be the next nation to do this with Vietnam, HongKong, Taipei. It sucks and Putin will be recorded in history as one of worst people on Earth. After Hitler. The next one can be Xi from China.
Even Ukraine have a old history and relations to Russia, it does not make sense when Putin sent army to this nation and destroy infrastructures, lives, economy, other things there just on sake of selfish privileges of Russia and Putin.
