The USA certainly tried to, but were rebuffed by the superpower of the time, Britain.
Anyway, back on topic, I don't think the corruption in Ukraine can be denied. Its every hit as bad as in Russia, and it could also be a wealthy country.
It's slightly more democratic than Russia, but only slightly.
So what, Canada only existed as a "country" for a few decades, maybe US military should bomb their cities and take it then.
