Pakistan can't change who it is.
AEI's Thomas Donnelly unearths what I think is a good insight into why the U.S. has so much trouble convincing Pakistan to do what Washington wants it to do:
'Pakistanâ??s problems are deep; indeed, they are embedded in the countryâ??s very identity. But our strategic interests are equally deep. The war in Afghanistan and the rise of India are indicators that the balance of power in South Asiaâ??â??â??like the balance of power in Europe, the Persian Gulf, or Pacific Asiaâ??â??â??is emerging as a core security concern of the United States and an increasingly important test of the international system.A coherent American strategy rests on convincing Islamabad of three things: that the United States has come to South Asia to stay; that Indiaâ??s rise should be met with strategic cooperation, not competition; and that playing a â??China cardâ? wonâ??t work. [Emphasis mine]
'
I don't think it's plausible to argue that America's interests in Pakistan run as deep as Pakistan's "very identity." Can you imagine what an outside power would have to do to change Washington's conviction that America is an exceptional nation created to spread freedom to the far corners of the Earth? Neither can I, which is why any strategy predicated on such a fundamental revolution in another country's political identity is destined to fail.
