Since terror is a tactic that can be used anywhere, the wonder is not the number of countries in which the US is fighting its war on terror, but that there are remaining where it is not. From Stephanie Sevall at tomdispatch.com:
In September 2001, the Bush administration launched the “Global War on Terror.” Though “global” has long since been dropped from the name, as it turns out, they weren’t kidding.
When I first set out to map all the places in the world where the United States is still fighting terrorism so many years later, I didn’t think it would be that hard to do. This was before the 2017 incident in Niger in which four American soldiers were killed on a counterterror mission and Americans were given an inkling of how far-reaching the war on terrorism might really be. I imagined a map that would highlight Afghanistan, Iraq, Pakistan, and Syria — the places many Americans automatically think of in association with the war on terror — as well as perhaps a dozen less-noticed countries like the Philippines and Somalia. I had no idea that I was embarking on a research odyssey that would, in its second annual update, map U.S. counterterror missions in 80 countries in 2017 and 2018, or 40% of the nations on this planet (a map first featured in Smithsonian magazine).
As co-director of the Costs of War Project at Brown University’s Watson Institute for International and Public Affairs, I’m all too aware of the costs that accompany such a sprawling overseas presence. Our project’s research shows that, since 2001, the U.S. war on terror has resulted in the loss — conservatively estimated — of almost half a million lives in Iraq, Afghanistan, and Pakistan alone. By the end of 2019, we also estimate that Washington’s global war will cost American taxpayers no less than $5.9 trillion already spent and in commitments to caring for veterans of the war throughout their lifetimes.
