The Washington Post reports: While Americans savored the last moments of summer this Labor Day weekend, the U.S. military was busy overseas as warplanes conducted strikes in six countries in a flurry of attacks. The bombing runs across Asia, Africa and the Middle East spotlighted the diffuse terrorist threats that have persisted into the final days of the Obama presidency — conflicts that the next president is now certain to inherit.

In Iraq and Syria, between Saturday and Monday, the United States conducted about 45 strikes against Islamic State targets. On the other side of the Mediterranean, in the Libyan city of Sirte, U.S. forces also hit fighters with the militant group. On Sunday in Yemen, a U.S. drone strike killed six suspected members of ­al-Qaeda in the Arabian Peninsula. The following day, just across the Gulf of Aden in Somalia, the Pentagon targeted al-Shabab, another group aligned with ­al-Qaeda. The military also conducted several counterterrorism strikes over the weekend in Afghanistan, where the Taliban and the Islamic State are on the offensive.

Militants in each of those countries have been attacked before, but the convergence of so many strikes on so many fronts in such a short period served as a reminder of the endurance and geographic spread of al-Qaeda and its mutations.

“This administration really wanted to end these wars,” said Paul Scharre, a former Army Ranger and Pentagon official now at the Center for a New American Security. “Now, we’ve got U.S. combat operations on multiple fronts and we’re dropping bombs in six countries. That’s just the unfortunate reality of the terrorism threat today.”

In meeting those threats, Obama has sought to limit the large-scale deployments of the past, instead relying on air power, including drones; isolated Special Operations raids; and support for foreign forces.

But militant groups have defied eight years of these sustained counterterrorism efforts.

Nowhere are the unexpected turns of Obama’s foreign-policy record more visible than in Iraq, where thousands of U.S. troops returned after the 2011 withdrawal to support local forces’ battle against the Islamic State. [Continue reading…]
