Currently the United States is assisting Ukraine against Russia by providing some non-lethal military equipment as well as limited training for Kiev's army. It has balked at getting more involved in the conflict, rightly so. With that in mind, I had a meeting with a delegation of Ukrainian parliamentarians and government officials a couple of weeks ago. I tried to explain to them why many Americans are wary of helping them by providing lethal, potentially game changing military assistance in what Kiev sees as a struggle to regain control of Crimea and other parts of their country from militias that are clearly linked to Moscow. I argued that while Washington should be sympathetic to Ukraine's aspirations it has no actual horse in the race, that the imperative for bilateral relations with Russia, which is the only nation on earth that can attack and destroy the United States, is that they be stable and that all channels for communication remain open.
