This was after US had already started bombing and that based was used for strikes inside Pakistan. At least check your facts before posting. from the article:
"ISLAMABAD, Pakistan — The
Central Intelligence Agency has vacated an air base in western Pakistan that it had been using for
drone strikes against militants in the country’s tribal areas, the Pakistani military said on Sunday.
So? what does this suppose to mean. Shamsi airbase was closed in 2011. And for your poor information the same based was used to strike inside Pakistan. US did not needed a base from Pakistan to strike in Afghanistan. Had that been the case why are strikes still happening in side Afghanistan? Again from your link:
"But a senior American counterterrorism official, speaking on condition of anonymity because the drone operations at Shamsi were classified, said
that vacating the base would not end American counterterrorism operations in Pakistan. “The United States retains robust capabilities to fight Al Qaeda and its militant allies,” the official said. “Our operations will continue.”
It wouldn't hurt if you read a bit before copy pasting articles from google.
Last i checked Abbotabad is in Pakistan, not Afghanistan and we were discussing Pakistan helping another country bomb Afghanistan. Makeup your mind what do you want to debate about?
