You're acting like that's the only policy point that exists. There are meaningful differences in other areas. I don't have enough non-propagandized information to argue for sure that there are differences in the middle east war department, but the parties certainly aren't the same on all war-related matters (see Ukraine/Russia as an example). Their rhetoric is different for the middle east but again I can't speak for their actions. And obviously their non-war policies are drastically different.
