Do you think the oil ministers in the middle east are raising oil prices so high it will tumble our economy?

By raising oil so high wouldn't our economy tumble and all them middle eastern terorist could just walk in and take over our country without sheding one once of blood, or can we be smarter then that,and try to find a way to not be so dependent on foreingn oil. Also are these canidates that are running for president who ever win will they stop that from happening or are we in trouble. I not sure either one of the canidates have what it takeas to protect us from what ever comes along, and some foreign dictatorship will take over this country and we will be in trouble.
