The US doesn't have the men, materiel and logistics to match their invasion of Iraq.

I doubt that standoff munitions and air defence missiles (let alone radars) have been replenished to any significant degree. Six F-35s have been delivered with the nosecone barbell weights, no radar.

The Iranians will have prepared a welcome, after all they are known for their hospitality.

I'd also read that Ansar Allah are prepping for a Saudi offensive.:

That would be singularly ill-advised.
