The story in brief is this:
ISI engaged its agents, directly or indirectly, to do the groundwork in advance for the noble cause to be carried out in Mumbai. Geelani a.k.a Headley, for example, was engaged to carry out recce while Rana was engaged via Headley, to provide material support for the cuase. Members of LeT, under the able leadership of the great great professor Hafiz, then carried out the noble cause. All of it happened under watchful eyes of ISI.
So you see, as much as you wish for it, there is still no disconnect.
This guy's claiming that LeT WAS NOT INVOLVED AT ALL. Please try to read his claims before trying to sound witty like you have done many times before.
