basically at some level, you understand that oil revenue is a big part of the funding for Middle Eastern terrorism / extremism. if you don't, your level of willful blindness is a bit disturbing, but fine.
for argument's sake, let's entertain the theory that oil revenue isn't funding terrorism and extremism. i still support replacing oil so that we have to be a lot less involved in that area of the world. even if we drill more of our own, oil is still fungible, and is thus affected by whatever is going on in the Middle East and in other hostile areas of the world. our involvement lets Saudi Arabia off the hook. they need to establish order in their own region, as we would be required to do should Mexico devolve into a civil war.
it's way past time to look ahead and consider other transportation fuel options that don't require the US to get involved every time there's some sort of unrest in that region, in my opinion.
i'll add this : every time that we are sucked into a war, wartime tax rates need to go into effect to pay for it, and the marginal increases need to be significant. perhaps that would make the hawks a bit less enthusiastic. if we're going to war, we need to have a national discussion, and then we need to pay for it.
