Most Iranians were not fond of him.
According the following link, it looks like he maintained a limited working relationship...

...but he certainly considered them heretical, and I doubt he would have been content to live among them.

And in spite of the official stance of the Iranian government, many Iranians are pro-US.

Yes I am listening to Darth Ender but the issue your avoiding is no matter the conflict between the two divisions of the Muslim faith, America and the West is the common enemy. IF many Iranians are pro-US as you put it (hard to believe considering Israel) Bin Laden being amongst them would've been refuted by ALL due to him being a MUSLIM despite all else. You seem to underestimate the sheer hatred these people have of the West.
