As of Nov. 19, the United States had conducted 6,471 of the 8,289 airstrikes against the Islamic State, according to the Pentagon. American warplanes carried out about two-thirds of the strikes on Iraqi territory and 95 percent of those on Syrian territory. Australia, Canada, France and Jordan have conducted strikes in both countries. Belgium, Denmark, the Netherlands and Britain have participated just in Iraq, while Bahrain, Saudi Arabia, Turkey and the United Arab Emirates have participated just in Syria.That leaves more than 50 other coalition members that have never been directly involved in the air campaign. Some early participants, like Saudi Arabia, Bahrain, Jordan and the U.A.E., have not conducted a strike in months. While France has stepped up its strikes since the Paris attacks, Canada’s new prime minister is sticking to his vow to pull its six CF-18 fighter jets out of the bombing campaign, although Canadian surveillance and refueling aircraft may stay with the mission.
