Forget about aircraft.
I am uncertain if you remember the blackout of 2003, as it probably didn't hit Texas, but it did hit the North-East pretty bad for a few days. That blackout was caused by a fallen tree which overloaded the grid, and led to cascading failures.
The grid is our biggest weakness. It is old, and interdependent, and vulnerable to attack. If we attack Iran, our infrastructure will be the target of retaliation.
The attacks on our infrastructure will unfortunately be quite cheap and have potential to cause a lot of damage. They will be difficult to stop, and easy to perpetrate.
Moreover, if US actually bombs Iranian oil fileds as you originally proposed, they will have very little else to lose.

China is not the only country that is at the mercy of USA to honor the dollar. A broke businessman that will default on his debts will find it hard to buy stuff in the future, no matter how much THE BANK will suffer.

A lot of US economy consists of marketing and selling products made in China. Slow down the flow of these products, and you'll see marketing executives getting the axe, and store chains, like Walmart raising prices, and importers going broke, and profits dropping, and stocks going down, and recession, and unemployment, and very unpleasant things. Its not about cheap plastic crap anymore.
I haven't seen a "Made in USA" label for a very long time.
We are all in this together, and we will all fall together.
