send troops to Ukraine to avoid the World War III

Putin is to become a new Hitler of 21st century. In 2008 Russians invaded Georgia and no one stopped Putin, in 2014 Putin occupied Crimea and invaded Ukraine, once again, the world does nothing significant to stop Putin, next will be Moldova, then all Georgia, then Latvia, Estonia, Lithuania, Poland, Czech Republic, eastern Europe, western Europe. You think it's not possible? In 1939 when Hitler invaded Poland, no one thought it would be possible he'd start the World War II, the consequences of which you know now. If we don't stop Putin ambitions now, the same is awaiting for the world now, but with much bitter consequences.
STOP PUTIN! Send NATO and US troops to UKRAINE.
