According to www.husainhaqqani.com
Husain Haqqani is former Ambassador of Pakistan to the United States (2008–2011). He is currently Senior Fellow and Director for South and Central Asia at the Hudson Institute and co-edits the journal ‘Current Trends in Islamist Ideology’ published by Hudson Institute’s Center for Islam, Democracy, and Future of the Muslim World.
Hussain Haqqani is the main actor of Memogate scandal.
According to Wikipedia,
On 12 June the supreme court commission released its findings and found that after testimony by all parties and verifying the forensic results of Ijaz's BlackBerry conversations with Haqqani it was "incontrovertibly established" that Husain Haqqani had written the memo and was being called back to Pakistan to face likely charges of treason.
Secondly, his recent writings suggest that he has a deep grudge on the state.
My question is, being one of the most prolific and senior Pakistani diplomats, what made him commit such an act?
ostensibly seeking help of the Obama administration in the wake of the Osama bin Laden raid to avert a military takeover of the civilian government in Pakistan, as well as assisting in a civilian takeover of the government and military apparatus
. You may agree or disagree, but certainly there are important reasons here... Why are you dismissing the "he wanted a civilian government" reason?
