You haven't a clue; none at all. Neither do you even know what Pipes has advocated, apparently.
You and your islolationist friends, who also see America's past through distorted lenzes, should, instead, look at facts, rather than through unfactual smoke & mirrors of your own daydreams.
Anyone who uses 'fantasist' in an alleged serious foreign policy article is both an idiot and a dialectical idiot at that.
