'Larry Silverstein, his unjust claim, the act that was the foundation of the claim and it's DIRECT connection to the topic is in the article Moe posted. Pointing out his foreknowledge unjustifying his claim and his complicity in the act is not off topic. It gives credence to the conspiracy that was also in the O.P.
There is proof that WTC7 was strategically weakened prior to being pulled as there is with the towers in the 45 degree cuts int the structural steel beams and the presence of thermite which is used to do exactly that. The NYFD describe the collapse as a series of booms (thermite charges also seen as tiny puffs going down the building ahead of above floors collapsing) "just like a demolition". Larry Silverstein confirmed it in a documentary on PBS. Are you telling Larry Silverstein who made the decision to pull the building that it wasn't pulled? He made it pretty clear.
As for the sequence, the charges aren't just set around file cabinets. They have to be on the steel columns themselves which are not visible from outside the building. Once whatever needed to be done inside WTC7 that morning was done, it didn't matter if a superficial fire was set or a separate explosion causing an externally visible damage as the building was just going to be pulled anyway. Logically there had to be some externally visible damage for the 'justification' for 7 to be pulled, though 3,4,5,and 6 were not. Of all the standing damaged burning buildings 7 was the least damaged. The reason WHY 7 was pulled would be the EXACT REASON Zurich Insurance would be at odds with LARRY SILVERSTEIN, THE FBI, THE PROJECT FOR A NEW AMERICAN CENTURY, and the BUSH ADMINISTRATION.
This makes the O.P. articles point that given the executive's connection and legal fight to deny double indemnity clause in the policy with Silverstein, there is very little likelihood that he committed suicide.

9/11 is in the title of the O.P. as is:
Zurich Insurance
2nd executive suicide
