Will IS Losses in Iraq, Syria Boost al-Qaida?

Joshua Geltzer was quoted on a VOA News article about the effects of recent IS losses in Iraq and Syria:

Al-Qaida had been largely eclipsed by IS in recent years, with IS militants grabbing headlines by seizing territory in Iraq and Syria and carrying out attacks in the West. But there are signs that al-Qaida may be re-emerging as a regional power.

"Al-Qaida in Syria is using opportunities to seize additional safe havens, to integrate itself into parts of the local population, parts of other forces, and bumping into other forces as well," said Joshua Geltzer, a former senior director for counterterrorism at the U.S National Security Council.

Tahrir al-Sham, an offshoot al-Qaida group originally known as the al-Nusra Front, has recently emerged as the most powerful Sunni insurgent faction in Syria after consolidating its control over most of the northwestern province of Idlib.
