Who is HH's mentor Ikram Sehgal?

Ikram Sehgal hints at Hussain Haqqani's "mentor" in the following passage. It is for the reader to guess if HH's mentors are the US neocons he has befriended, or the co chairman of the handwritten will, or the sahripovs-in-waiting or the country he purportedly serves ~~~t

Whether delivered by regular diplomats or successful practitioners of the art does not matter, of critical importance to Pakistan is that our moderate message must have positive effect. The major focus is in the US capital, Washington DC. Ambassador Haqqani is an effective lobbyist, the question is, can he put the interests of his mentor over that of the country? These have coincided till very recently, what happens when they diverge? Maybe Haqqani, who has changed ideological sides often, may be too smart for his own good in a city that quickly spots phonies. One would rather have in place a diplomat of credibility and stature, Haqqani could successfully service a contract for being the country's lobbyist in Washington DC. On the other hand patriotically motivated Husain Haroon has been a revelation in the UN, performing brilliantly in promoting Pakistan's cause over everything else.
