As U.S.-Pakistani relations plunge to new depths, Americans need to look beyond media reports on tactical issues such as aid and counterterrorism. The direction Pakistan takes will be of great strategic significance to the world. The manner in which my husband, former Pakistani ambassador Husain Haqqani, is being treated in our homeland reflects the shrinking political space there for anyone who advocates positive relations with the West or stands up for religious-cultural tolerance and pluralism.

Husain resigned in November after successfully making Pakistan’s case in Washington for more than three years. He was implicated in a controversy sparked by an unsigned memo sent to Adm. Mike Mullen, then the chairman of the Joint Chiefs of Staff, after the U.S. raid inside Pakistan to kill Osama bin Laden in May. The memo, written by a Pakistani American businessman, ostensibly sought U.S. support for Pakistan’s civilian government against its military. The idea of an elected government seeking foreign help in reining in its military leaders is anathema to Pakistanis, who are rightly protective of our national sovereignty.

Mullen has said he did not consider the memo credible. Former national security adviser Jim Jones, who passed the memo to Mullen, has said that he saw it only as the creation of its author. Unfortunately, U.S. officials considered the memo so unimportant that they did not bother to promptly set the record straight regarding Husain; this allowed misinformation to spread in Pakistan, inadvertently creating concerns that should have been nipped in the bud.

After he resigned, Husain could have stayed in the United States. But he returned to Pakistan to seek an impartial inquiry into the controversy. Some in the Pakistani media, illustrating how our society has been poisoned by extremist views, launched a propaganda campaign accusing him of treason. Last month Pakistan’s Supreme Court barred him, on national security grounds, from leaving the country while a judicial probe is conducted. Husain appeared in court Monday and was asked for evidence of his innocence — even though no charges have been officially leveled against him. Human rights lawyer Asma Jahangir and other legal experts consider the court’s order of an inquiry a denial of due process. A country’s highest court should be the last avenue of appeal, not the first stop. In a democracy, the rights of a citizen should not be trumped by an intelligence service’s assertions of national security interests.

But my husband’s case is not simply that of an individual who has been wrongly accused and denied due process. It is part of a broader issue: the systematic elimination or marginalization of every intellectual and leader in Pakistan who has stood up to the institutionalization of a militarized Islamist state. Ever since the military dictator Mohammed Zia ul-Haq created the well-oiled machine of religious extremism, Pakistan’s progressive and liberal voices have faced allegations of treason and corruption.

Former prime minister Benazir Bhutto endured persecution and exile before she was assassinated in December 2007. She was vilified by extremists for standing up to their beliefs and for her valiant efforts to move Pakistan toward modernity, pluralism and democracy. Her widower, Asif Ali Zardari, has been hounded by those same forces since he was elected president in 2008. Insidious media campaigns, judicial actions and open threats have repeatedly been used to thwart the results of elections.

Last January, Salman Taseer, the governor of Pakistan’s largest province and a progressive politician who promoted the rights of religious minorities as equal citizens, was killed by one of his guards after media characterizations convinced the man that Taseer was not a true Muslim. Shahbaz Bhatti, federal minister for minorities, was gunned down two months later for voicing the belief that non-Muslims in Pakistan must have rights equal to those of the majority. Against this backdrop, for security reasons, Prime Minister Yousuf Raza Gilani is hosting Husain at his Islamabad residence while my husband deals with the malicious allegations and sinister campaign against him.

Husain was ambassador to Washington during a period when U.S.-Pakistani ties became acrimonious. He worked diligently not only to bolster Pakistan’s image but also to shift the relationship from a transactional basis to a strategic alliance. He sought to expand relations into a bond in which the people on each side respected the other. His vision for Pakistan matches the one Bhutto held: a modern, moderate, Muslim, democratic and pluralist country with close ties to the United States and that is also protective of its sovereignty.

Husain’s tireless efforts to build a tolerant nation integrated into the world community aligns with both Pakistani and U.S. interests. He knew that his views were not popular in Pakistan but hoped that over time the majority would adopt his vision. He could have followed the path of least resistance and taken a populist stance, blaming Washington for Pakistan’s ills. This is fashionable in Pakistan. That would have helped him gain popularity and maybe even support from the military establishment, which never forgave him for the 2005 academic book in which he criticized the military’s expanded role.

Pakistan’s judicial process over the disputed memo might be an internal matter, as the U.S. State Department has said. But it is imperative that Americans stand up for someone who sought to improve U.S.-Pakistani relations and spoke out for our shared values. The manipulated investigation over an unsigned memo that produced no tangible results should not be allowed to undermine Pakistan’s democracy or to punish a good man for his forward-thinking vision.
