The success or failure of President Barack Obama's new Afghanistan strategy will depend on numerous international factors, from the contributions of Washington's NATO allies to the performance of Afghanistan's beleaguered government.
However, few factors loom larger than Pakistan.
Indeed, the Obama administration has conceded that unless Islamabad intensifies its efforts against Taliban and al-Qaida forces based in Pakistan, the Afghanistan plan will likely fail. Predictably, the U.S. government has renewed pressure on Pakistan to launch a more aggressive campaign against militancy within its borders.
However, Washington has little credibility and leverage in Pakistan, and Pakistani mistrust of the United States runs high. According to one poll from earlier this year, 64 percent of Pakistanis regard America as an enemy, and only 9 percent see it as a partner. Such sentiments pose a major challenge to the development of an expanded strategic partnership with Pakistan, which Obama reportedly offered to Islamabad in recent weeks.
Given these unsavory views of the United States, Washington's appeals for stronger Pakistani action against extremism could easily fall flat -- unless they are accompanied by similar pleas from nations with more credibility in Pakistan.
