How much oil do we actually get from Iran?
Do you understand the open international market of oil?
Do you understand simple capitalism supply and demand?
Taking so much oil off the market will decrease the amount available thus causing the price to increase.
Remember the Iraq war. All that oil was taken off the market because of the war. By the summer of 2008 the price of a gallon of gas was well over 4 dollars a gallon.
I fully expect the price of oil to be over 5 dollars a gallon before trump is finished.
It's already three and a half dollars a gallon here. I drive a Prius that only holds 10 gallons. It costs me over 30 dollars to fill my car. When it cost me around 20 dollars to fill my car in the Obama years.
It's what happens when we have a republican president. The price of oil goes up and we all suffer while making nations in the middle east who hate us even more filthy rich.
