The Islamic State’s mass execution of Egyptian Christians is the latest sign that ISIS is pointing its sword against not just the West but the rest of the Arab world — drawing the region into a spreading war that leaves the United States in a difficult spot as it tries to marshal a cohesive coalition.
That coalition started last fall as a U.S.-led airstrike campaign involving several Gulf states, and Jordan. Not only have a host of western nations since joined to offer at least financial support, but several other countries in the Middle East and North Africa are now launching their own military campaigns.
On Monday, Egyptian warplanes struck at ISIS militants in Libya, in retaliation for the mass execution of Coptic Christians from Egypt. The airstrikes reportedly were coordinated with the Libyan government.
