As the Sunni states give their support for Obama’s anti-ISIS coalition, it’s worth remembering that another locus of chaos has these countries very worried: Libya. The spillover from that failed state has significantly increased the terror threat to Egypt. A number of jihadist groups, apparently, are connecting with each other within the country, much to the alarm of Egypt’s security apparatus.According to a recent Reuters report, the terrorists based to Egypt’s east, in the Sinai and Syria, and on the Libyan border to the west are making contact with and influencing each other. Officials say the Sinai-based Ansar Bayt al-Maqdis has formed ties both with ISIS and with the Libya-based militants. Meanwhile, the jihadists in Libya have been inspired by ISIS and are traveling back and forth across the Egyptian border. As one Egyptian official told Reuters, “There is definitely coordination between Ansar, the militants in Libya and Islamic State leaders.” On top of that, there are thousands of Egyptians fighting for ISIS in Syria and Iraq, raising the same question for Egypt that most of its neighbors have: What to do when they come home?That is a combustible mixture, even for a country with a powerful military like Egypt’s. President Sisi might find it increasingly tempting to push the terrorists based in Libya back to a manageable distance. The Sunni states already proved their willingness to act, even without U.S. approval, when the Egypt and the UAE conducted airstrikes late last month. It’s possible that we haven’t seen the last of Sunni interventionism in Libya.
