Pakistan hasn’t been in the news much lately, and the Washington Post‘s David Ignatius thinks there is a very good reason for that: its relationship with the United States has been “reset”, with both countries relieved to take a step back from their often stressful partnership. According to Ignatius, “the two nations [will] still cooperate but with less intensity and visibility.”2011 was not a good year for U.S.-Pakistan relations. In January, a CIA contractor killed two Pakistanis. Five months later, Navy Seals stormed Osama bin Laden’s compound in Abbottabad without first warning Pakistani counterparts out of fear bin Laden might be tipped off. And in November, U.S. aircraft mistakenly attacked and killed 24 Pakistani soldiers. Pakistani nationalists, always suspicious of US designs and especially so as the US and archenemy India have drawn closer, seethed with rage. After the November airstrike, Islamabad responded by cutting off supply-road access to U.S. forces in Afghanistan.Perhaps, as Ignatius contends, this tumult has naturally subsided into a “cooling-off period.” But another explanation for the relative calm is that Pakistan may simply be biding its time as the deadline for the U.S. withdrawal from Afghanistan nears.
