The news today that U.S. air strikes have killed three key Islamic State leaders cheered me a little.

Then reality set in almost immediately: There will be others to step in to replace these murderous monsters.

The White House and the Pentagon couldn’t confirm until recently that the three ISIL leaders had been killed by American pilots. The news is good, to be sure. Pentagon officials say the deaths of these three individuals has “degraded” ISIL’s command and control capability. “We believe that the loss of these key leaders degrades ISIL’s ability to command and control current operations against Iraqi Security Forces, including Kurdish and other local forces in Iraq,” Pentagon spokesman Rear Admiral John Kirby said.

OK, so what now?

Well, we keep launching air strikes and we keep killing the leaders of this terrorist cabal.

As we’ve learned in the fight against al-Qaeda, killing key leaders doesn’t mean the end of a group’s ability to function. We killed Osama bin Laden, but al-Qaeda lives on.

ISIL won’t die a quick death. It will require continued vigilance and diligence on our part to ensure that the terrorists remain “degraded.” Then we must destroy them.
