ISLAMABAD, Pakistan — Relations between the United States and Pakistan often have a through-the-looking-glass quality, where almost nothing appears quite the same from the other side. The latest example is the case of Aafia Siddiqui.

In the United States, authorities say Ms. Siddiqui, a Pakistani neuroscientist who once studied at the Massachusetts Institute of Technology, is suspected of having links to Al Qaeda. She was convicted by a New York court in February of trying to kill American military officers while in custody in 2008 in Afghanistan. She faces life in prison when she is sentenced in May.

In Pakistan, she has become a national symbol of honor and victimization so potent that politicians of all stripes, Islamists, the news media and an increasingly anti-American public have all lined up to champion her claim of innocence.

In a rare display of unity, Prime Minister Yousaf Raza Gilani, who has described Ms. Siddiqui as a “daughter of the nation,” and the opposition leader, Nawaz Sharif, have promised to push for her release. Last week, senators passed a resolution to demand her return to Pakistan.
