Iran would only be a threat to the SAudis -- that's why the Wahabbi Saudis are running scared and getting the US to curb Iran
The single greatest threat to world stability today is Pakistan, A Sunni country
“Iran would only be a threat to the SAudis”
You mean, after they annihilate Israel, as they have promised to do? Or after they are done propping up the Assad regime and murdering thousands in Syria? Or after they have virtually annexed what’s left of Iraq? Or after they’re done beating down ‘their’ Kurds, a truly oppressed ethnic group that really does deserve its own state? They happen to also be a threat to the Saudis, who at least are concerned with their profits on the oil market, which makes them predictable.
