The countries that have nukes and can reach us are not fundies who don't value human life. They have not openly called for the complete destruction of America.
But to think a nuclear Iran wouldn't have an effect on us is naive. Economic variability/shockwaves, potential for attacks, pain to our allies, etc all would hurt us.
It's also naive to think they wouldn't continue to develop missles with longer ranges.
They've done nothing to earn the benefit of the doubt.
If we could go pure isolationist and not suffer for it, I'd say have at it. It's just not reality.
I don't agree obviously. Do you know Iranian culture, have you like looked into it? Do you know some of the differences between Shia and Sunni? Iran isn't the biggest state sponsor of terrorism, what they do is threaten Israel over the Palestine question, that's the whole problem. The US is the biggest state sponsor of terrorism. I mean even Trump said Obama created ISIS. Look at the links between Israel and Hamas, the US and Al Qaeda. Look at how Trump praises Al Jolani, an Al Qaeda guy involved in killing Americans in Iraq. The US spent a very long time and tons of money to fund terrorist groups to topple Assad. Have you seen Tucker's 9/11 documentary? He doesn't claim much for certain but asks some very pertinent questions as to who was involved.
As the MIT professor missile expert Ted Postol says, Iran has had the capability to make nukes for a long time. He argues that Iranians aren't irrational crazed actors. Among other things, Iran hasn't wanted nukes because of the guaranteed result if they do: other states will immediately get them too, like Saudi and Turkey. That would threaten Iran too. Now Iran really has an incentive to go for a bomb and Postol speculates they could likely do it right now if they wanted to. But it's extremely risky for Iran for several reasons. If they were simple fundies who wanted to suicide themselves just so they could destroy Israel and the US they would do it. Why not?
What do you suggest Israel and the US do about the nuclear capability? Conventional weapons can't touch the deep underground facilities. Even bunker buster nukes might not do it. Even Trump says it, the US has to snatch it or otherwise force them to surrender the material. Like I say all the time, US and Israel might resort to nukes to "break" Iran. The other is building up a force for a couple of years to invade Iran. It takes time to set up logistics and the US probably doesn't even have the manpower as some suggest like a half million troops required. Robert Kagan hints at being for it, he doesn't say it directly.
