Well, the war means profits as much as the peace means profits, won't you think? It's just about who gets what kind of profits..
Overall, I think the recent political unrest plays more in favour of European economic interests than of the US. Compare the major consumers of Libyan and Syrian export oil, recall what countries were the most active players in the military intervention in Libyan civil war and make your own conclusions.

I think all these calls that the US is responsible for just about anything are not that wise, there are other influential players around.
