Evil did not disappear with the fall of the Berlin Wall and the collapse of the Soviet Union. Of course, many enemies of the free world were indeed destroyed when the Iron Curtain fell. Others saw their power and reach greatly reduced.
And some, like a cancer in remission but not entirely eradicated, bided their time and waited for better conditions to return.
Now there are once again enemies not only at the gates, but well inside the gates, and, after 25 years of complacency, Europe is culturally, militarily, and rhetorically unprepared to fight them off.
The beloved European soft power tools of economic and political engagement do not deter or weaken an aggressive dictator like Vladimir Putin—they encourage him.
The openness and charity that represent the great European Union experiment at its best also make it all the more vulnerable to terrorist groups like Islamic State and the disruptive impact of immigrant groups that do not return that openness and charity—or in fact resent it.
