Ok, please explain how our two embassies in Africa were brought down with the same kinds of truck bomb. How were the Kohbar towers brought down by a truck bomb that was in the parking lot. How was our embassy in Beirut brought down by a smaller truck bomb than the one in OKC?

You have to judge each situation on the individual facts.
