This is definitely the US's headache, not Pakistan's. I see a lot of logistical issues sending it through central Asian countries than straight through Pakistan. Pakistan is the ideal route, & if the US is trying to reduce its dependency on Pakistan, it will encounter huge headaches trying to 'rectify' that problem. People also need to realize that drone attacks are dependent on the supply lines, & there is no quicker route than through Pakistan. This could seriously hamper the US's efforts on the WOT, as they would incur high costs with their supply routes through central countries, as well as the extra time that will be consumed using that route. This is definitely a good thing for Pakistan, as it needs to distance itself as far from the US as possible. I think the WOT has went past the point of 'leveraging'.
