I think that he thinks that he's doing the right thing. I think he thinks that installing US hegemony in the Middle East would be beneficial for the US. Regardless of whether it is or not, I believe that it is wrong to impose your beliefs on someone else, which is what this action I posit he's making is. In addition, I don't believe that it's beneficial, as it's more likely to piss off more people while installing a new government, a process with which the US does not have a good track record.
