No US bases but bases the US uses. Close enough really. You site was useless to prove you point, so I googled it myself. Thanks anyway.
>>In Pakistan, the Pervez Musharraf government has allowed the commercial airport at Jacobabad, about 420km north of Karachi and 420km southeast of Kandahar, as one of three Pakistani bases used by US and allied forces to support their campaign in Afghanistan. The other bases are at Dalbandin and Pasni. Under the terms of an agreement with Pakistan, the allied forces can use these bases for search and rescue missions, but are not permitted to use them to stage attacks on Taliban targets. Both Jacobabad and Pasni bases have been sealed off and a five-kilometer cordon set up around the bases by Pakistani security forces.
Reports of increased US operations in Pakistan go back to March 2004, when two air bases - Dalbandin and Shahbaz - in Pakistan were the focus for extensive movements to provide logistical support for Special Forces and intelligence operations. Shahbaz Air Base near Jacobabad appeared to be the key to the United States' 2004 spring offensive. At Jacobabad, C-17 transports were reportedly involved in the daily deliveries of supplies. A report in the Pakistani newspaper the Daily Times on March 10, 2004, claimed that the air base was under US control, with an inner ring of facilities off limits to Pakistan's military.
