The message the author conveys about society here is that the idel we might have from society help us understand reality of society with more easiness that the perfect society because it is very difficult to protray it.

After the events that took place after 9/11, the U.S invaded Afghanistan. But I don't remember hearing about an "alliance" but they did have some what a alliance with United Kingdom and the Taliban. See if you look back at history they blamed Osama Bin Laden for the attack on 9/11 so there is no way they had an alliance especially since Osama was wanted in the FBI. In fact the president back then (George W Bush) demanded the Taliban to hand over Osama but the Taliban wanted proof that Osama's involvement in 9/11
There was never an alliance with Osama Bin Laden.
