None of this is to say that US power and influence are worthless. Far from it, but there are serious constraints on how effectively that power can be exercised — and grave consequences when it is wrongly applied.
As history has consistently shown, the US faces enormous barriers in affecting events in faraway lands that have their own political, ideological, religious and ethnic idiosyncrasies.
In this sense, what is so often dismissively labeled as retreat, withdrawal or isolationism is, in reality, restraint and pragmatism on the global stage — acknowledgment of the limits on US power; recognition that Americans are tired of foreign misadventures; and an understanding that even the best of US intentions can lead to the worst possible results.
