Can we for a second, step back and acknowledge who CAUSED the instability in those countries? Iran, off the top of my head, had a secular democratic government until the CIA orchestrated a coup.

Meanwhile, I certainly don't trust a country with nukes that has single handedly spearheaded a genocide that has resulted in the death of over 20 thousand children. Its literally a magnitude order more deaths per year than any other armed conflict. If you want to argue that religious zelots should not be trusted with nukes, I fully agree with you. but lets apply that logic to all countries. not just the ones that "ally" with us.
