"very odd"
It makes perfect sense if, in his state of delusion, i'manutjob thinks an attack on iran would unite muslims and the arab world againstthe infidels.
That doesn't pass the smell test. Ahmadinejad is Persian. He doesn't want Arab help; he wants to crush Arabs. "Uniting" Arabs is the last thing that Iran (read: Persia) wants.
Persians and Arabs have been at war for thousands of years longer than Islam has existed, and will be at war for thousands of years after Islam is long gone.
It's genetic.
