Its often supposed that Bitcoin arose as a reaction to the financial crisis, but that reaction is just as likely to have come from someone who was fed up with the government, as is it to come from the government. So your list of dates doesn't really count either way.
I see two main possibilities: (1) the paper was prepared anytime in advance and withheld until the dollar/US/world faced serious risk. (2) The BTC paper was started in the early stages of the crisis or later.
Both possibilities could suggest the BTC creators had an interest in the success of the dollar. The alternative would be that it was opportunism of BTC creators who were always against the dollar or turned on it in the crisis. I happen to think that if you were always against the dollar you would just release bitcoin immediately and hope for the most disruption. I'd think that someone supportive of the dollar would be more apt to release it strategically as a contingency.
In my mind that means that dollar supporters are the better chance of being behind bitcoin because they could have made it any time in the past or as the crisis progressed, whereas dollar opponents only had the time of the crisis to make it.
Assuming that, I think then the US has an above-average chance of being the authors of bitcoin.
