OkBomb:
The head of Elohim city was an FBI informant.
the security chief of Elohim city was an FBI informant and a German intelligence agent.
his girlfriend Carol Howe was also an FBI informant, and the bomb still exploded.
the sloppy, corrupt FBI (now headed by a more corrupt HSBC operative) covered up most of it.
the role of Muslim middle easterners is still not clear.
From your wording, it sounds almost like you think the government wanted to prevent the bombing, but failed.
