The promise of the "global war on terror" was that "it was better to fight them there than here." That promise brought mass violence to Iraq, Afghanistan, Pakistan, Palestine, Yemen and Somalia -- in the name of peace in the West.
That formula has clearly failed. Tuesday's bombings in Brussels come on the heels of similar incidents in Grand-Bassam, Ivory Coast; Maiduguri, Nigeria; Istanbul; Beirut; Paris; and Bamako, Mali, all in the last six months. Rather than containing violence, the war on terror turned the whole world into a battlefield.
We should not be surprised. Violence inflicted abroad always comes home in some form. Last year, the U.S. military dropped 22,110 bombs on Iraq and Syria. The Pentagon says these bombs "likely" killed only six civilians, along with "at least" 25,000 Islamic State fighters. The true number of civilian deaths, though, is likely to be in the thousands as well.
