In the context of the United States' War on Terror, Central Asia has once again become the center of geostrategic calculations. Pakistan's status has been upgraded to a "major non-NATO ally" because of its central role in serving as a staging point for the war in Afghanistan and for providing intelligence on Al-Qaeda operations in the region. Afghanistan, which had served as a haven and source of support for Al-Qaeda, under the protection of Mullah Omar and the Taliban, was the target of a U.S. invasion in 2001, and ongoing reconstruction and drug-eradication efforts. U.S. military bases were also established in Uzbekistan and Kyrgyzstan (the Uzbek presence was later withdrawn), causing both Russia and China to voice their concern over a permanent U.S. military presence in the region at a time when disengagement with Central Asia was considered detrimental to American long-term security interests. At the same time, US strategic thinking was urged to be of a lower profile to avoid perceptions of the US as a regime patron.
