Ryan Faith: Why Russia spent 2015 half-assing it in Ukraine

What went on in Ukraine in 2015 (after Russia sneaky-invaded the country in early 2014 and annexed Crimea) was not a Cold War or frozen conflict, where the shooting and killing lie either in the past or in a potential future. Nor was it a hot, high-intensity fight in which two countries spent their blood, toil, tears, and sweat on an existential battle to the death. It wasn't even an American-style quagmire like Vietnam, Iraq, or Afghanistan.
