It is true that the US military is probably a little overextended at the moment, making an Iraq-style invasion unlikely. That said, the forces, equipment, and logistic stockpile that is already in place in the the theater, and the region would allow the US to mount a full-blown Shock and Awe air-campaign, without having to do much in the way of prepositioning.
The maxim that air power alone cannot win a war, still holds true- but being attacked by aircraft of the US military certainly blurs the distinction.
They can achieve air superioty, without incurring significant losses, they can saturate and destroy Iran's air defenses with vitual impunity, and they can mount sortie after sortie at all times, in any weather.
What's more, the US can brutalize Iran unilaterally, without requiring the assistance, or permission of any nation.
