The US has been directly or indirectly involved in all conflict in the middle east in the past few decades, and the instability in the region is due to the US's failed foreign policy.
Maybe the US should stop pretending they know what they're doing. The US can't keep domestic terrorism at bay, why are they trying in a foreign setting?
And yeah, the US should get out of the Middle East - we need to stop pretending is that sharia-law is compatible with western liberal democracies*.
* This IMO is the socio-cultural reason for the Middle East's instability following the US’s interventions - and why similar interventions had more success elsewhere.
Also, speaking frankly, there's an implications that people don't want Iran to have nuclear weapons because it's a Muslim country. This is false. It would be far palatable for Saudi Arabia or the UAE to develop nuclear arms because even though neither country is 'Christian' or 'democratic', they are at least allies.
