This essay by New York University law professor Thane Rosenbaum is worth your time. Key paragraph:

Obama was notably, if not pathologically, anti-colonial, appeasement-friendly, condemning of American exceptionalism, and endorsing of conciliation at almost any price—as we now see, even at the risk of jeopardizing the security of America’s allies.
