I beg to differ. The Ukraine isn't the world's most corrupt country. It is number 116 out of 180 countries.
It isn't even the most corrupt country in Europe; only the second-most - after Russia.
I can understand why Americans don't want to support Ukraine and why you are dead tired of being entangled in Europe's and Asia's wars. I don't blame you if you bail out.
Unfortunately, as a European, I cannot just leave Ukraine to its fate. The fact is that Ukraine is not a threat to me, but Russia is. And the way the Russians treat their "brothers" in Ukraine leaves me worried how they will treat others.
