Yeah, that's the whole problem. Putin sees himself as a 21st Century Tsar and is on this quixotic quest to restore the Russian Empire. He actually thought his troops would be welcome with open arms in Kiev.
Well, this little "special military operation" (looks like a war to me) has cost the lives of hundreds and thousands of Russian soldiers. And, of course, decades of bridge building with the world has been wiped out.
Is it worth it, Vlad?
