It is not clear why talk of (thus far) modest reductions in the Fed’s large-scale asset-purchase program should have had such big repercussions outside the United States. The best economic explanation is that capital has been flowing out of emerging markets in anticipation of future rises in U.S. interest rates, of which the taper is a harbinger. While plausible, that cannot be the whole story.

For it is not only U.S. monetary policy that is being tapered. Even more significant is the “geopolitical taper.” By this I mean the fundamental shift we are witnessing in the national-security strategy of the U.S.—and like the Fed’s tapering, this one also means big repercussions for the world. To see the geopolitical taper at work, consider President Obama’s comment Wednesday on the horrific killings of protesters in the Ukrainian capital, Kiev. The president said: “There will be consequences if people step over the line.”

No one took that warning seriously—Ukrainian government snipers kept on killing people in Independence Square regardless. The world remembers the red line that Mr. Obama once drew over the use of chemical weapons in Syria . . . and then ignored once the line had been crossed. The compromise deal reached on Friday in Ukraine calling for early elections and a coalition government may or may not spell the end of the crisis. In any case, the negotiations were conducted without concern for Mr. Obama.

The origins of America’s geopolitical taper as a strategy can be traced to the confused foreign-policy decisions of the president’s first term. The easy part to understand was that Mr. Obama wanted out of Iraq and to leave behind the minimum of U.S. commitments. Less easy to understand was his policy in Afghanistan. After an internal administration struggle, the result in 2009 was a classic bureaucratic compromise: There was a “surge” of additional troops, accompanied by a commitment to begin withdrawing before the last of these troops had even arrived.

Having passively watched when the Iranian people rose up against their theocratic rulers beginning in 2009, the president was caught off balance by the misnamed “Arab Spring.” The vague blandishments of his Cairo speech that year offered no hint of how he would respond when crowds thronged Tahrir Square in 2011 calling for the ouster of a longtime U.S. ally, the Egyptian dictator Hosni Mubarak.
