This is going to be worse than Iraq and Afghanistan combined . Iraq and Afghanistan were no threat to the US military and it cost us over a trillion dollars to fight both countries, Iran on the other hand has been preparing for this for a long time. They've been spending heavy money on their military since the 80's. This cheeto is going to destroy this country economy, AGAIN!!!
They just need to find a new focal point for a hate campaign and stroke fear, Iran fits the bill, ISIS is pathetic and China is out of the question.
The problem is ability, the US is not able to attack Iran at the moment.
The diplomatic and economic avenues have been closed by the P5+1 Nuclear Deal, and the US will never again get UN authority to do anything.
This only leaves an illegitimate solo strike against Iran probably with Israel.
If they do this crazy action, there will be no limits, no such thing as a limited air campaign.
If you hit Iranian sites, you will lose Iraq. Afghanistan's government also equally depends on Iran as much as the US and they can pull the plug of support. $6 trillion on both of those projects since 2001 and you lose both due to a war with Iran.
You will have daily missile strikes on Bahrain's US bases and the temptation to put boots on the ground to "defend allies" will be irresistible.
You'd piss off countries like India, Turkey, and South Korea who are US allies benefiting from Iranian trade and energy. You'd effectively destroy or damage parts of their economies.
If you are stupid enough to start a war with Iran you are stupid enough to invade and the US doesn't even have half the manpower necessary and it would cost trillions.
Lets wait and see, but this sounds like bluffing and bluster.
