An anonymous expert within the Kazakh Defense Ministry said that "of all the assistance can offer towards military counter-terrorism operations—allowing use of our airfields, opening air corridors and sharing intelligence information—the last would be the least risky for Kazakhstan. Allowing the use of airfields means going into direct confrontation with the Taliban, and that is not a good scenario in our situation." An anonymous, high-ranking Foreign Ministry official said "the influx of refugees" created by U.S. airstrikes in Afghanistan "is one problem, but the greater problem is that terrorists and militants might flee northward disguised as civilians." Professor Murat Abdirov, director of the International Relations Institute of Eurasian University, said, "Kazakhstan cannot stay away from the international anti-terrorism coalition, but we should proceed with caution."
