Iran could put a lot of troops on the ground, yes.
In truth, unless the Russians have seriously upgraded the Iranian conventional war making capabilities, Iran’s army could just about fight Jordan to a draw. For all their agitprop, the Mullahs don’t have an effective conventional arms industry in country and their much ballyhooed new weapons are mostly vaporware.
Asymetrical warfare might work for them for a bit, but not having any real punch in the desert makes the Iranian rhetoric sound very hollow to me. Why else would these nutjobs seek nuclear armaments with so much fervor?
I expect the Israelis to act as our proxies in this matter. They will repeat the Iraqi nuclear plant strike in Iran. I believe the fly-over they staged over Iran last spring? was a dress rehersal and a warning to the Iranians, which the Iranians will ignore.
