It's hard to comment on most of the speculation revolving around the parties involved/guilty as it is at the moment pure speculation. Until the facts are released to the public we are just stoking the fire.
There must be a reason as to why the US haven't released what they know via satellites and their sources. I think they will have the most complete picture currently.
The loss is still raw and people are understandably raw with anger and anguish.
There are so many aspects to this I forsee it will take quite some time to understand it fully.
