Most of the more prominent past Chechen separatist leaders have died or have been killed, including former president Aslan Maskhadov and leading warlord and terrorist attack mastermind Shamil Basayev. Meanwhile, the fortunes of the Chechen independence movement sagged, plagued by the internal disunity between Chechen moderates and Islamist radicals and the changing global political climate after 11 September 2001, as well as the general war-weariness of the Chechen population. Large-scale fighting has been replaced by guerrilla warfare and bombings targeting federal troops and forces of the regional government, with the violence often spilling over into adjacent regions. Since 2005, the insurgency has largely shifted out of Chechnya proper and into the nearby Russian territories, such as Ingushetia and Dagestan; the Russian government, for its part, has focused on the stabilization of the North Caucasus.
