However, if the security aid cut-off is viewed as a first step in a progressive squeeze of Pakistan, resulting in US pressure at the IMF and WB, then the equation changes completely. To understand this it is best we look at a cost benefit analysis from the Pakistani point of view. First, should Pakistan cease cooperation and cut of the air and land supply route to Afghanistan, the US has no alternate supply routes with Russia and Iran being hostile. Moreover this is exactly when Pakistan's terror assets become even more salient. The web of terrorists Pakistan has created, is a significant military and economic asset. Using these assets deftly in the past has brought Pakistan "strategic salience". This takes two forms - nuclear and intelligence. Its use of terrorism in Afghanistan means that it is also the primary provider of intelligence to the US on terrorists of its own making. In short America will suffer a significant operational blind spot if it loses Pakistani intelligence, no matter how counterproductive that intelligence is. On the India front, Pakistan uses terror attacks to maintain the myth of the India-Pakistan border being the world's most dangerous nuclear hotspot. Again the drips of intelligence and cooperation it provides to the US on its military nuclear programme mean a whole lobby exists in the US. This lobby would believe that even this rudimentary access is critical to peace in the region. It is not exactly wrong - the moderating influence that the lobby exercises on Pakistan, probably, to some extent, prevents Pakistan from taking an even more extreme nuclear posture. The only problem is while both the Intel and nuclear lobbies believe they are moderating the Pakistanis, it is in fact they who dance to a carefully calibrated Pakistani tune, where engagement leads to fake cooperation - essentially a blackmail model. Because the intel and "restraint" offered are not quid pro quo for engagement, but rather a predetermined necessity for the Pakistani state, passed off to its interlocutors as a major concession.
