Dude not all armor are tanks, tanks are a very specific type of armor designed to dominate land warfare with high caliber weapons systems that can be direct fired on the run. Tracks and metal don't a tank make. A Paladin has tracks, armor and a really big gun but is most certainly not a tank. A Bradly also has tracks, armor and a much smaller gun, but again isn't a tank. The Hercules has tracks armor and mounts a machine gun, yet again isn't a tank. The Wolverine has tracks, armor but no weapons. Then you have something like the Stryker which doesn't have tracks but has armor, a cannon and carries troops. The Humvee doesn't have tracks but can be armored and mounted with an automatic grenade launcher, talk about scaring the piss out of an entire enemy company.
Furthermore,
The US is now Oil and Gas independent. We are actually an oil / gas exporting nation but due to laws we can only export refined fuels like gasoline / diesel and not crude oil. Also we sell it on the international market so our oil / gas is competing with other exporting nations for world demand which includes our own. This is how people can get all sorts of screwy numbers based entirely on how the person running the number chose to count things. We produce more Oil / Gas then we use but because we're selling it on the open market it's entirely possible for us a US company to purchase gas from a foreign nation while another foreign nation buys our own.Back to oil. You implied the U.S. gets a majority of its oil from the Middle East. I have shown you clearly this is not the case. It is not even close. What we do buy, we do not need. Unbeknowst to you, it has been U.S. policy since the late 70s to buy enough to maintain some influence, but not enough to have any measure of real strategic impact if sourcing stops (either by decision on the U.S. end or circumstance on the ME end). Again, you are out of your depth.
