This was my thinking as well. Iran sending a nuke at anyone effectively is the end of Iran (and many of its people). Something something…mutually assured destruction (e.g., North Korea has nukes, makes threats, doesn’t use them)
Unfortunately MAD in the classic sense doesn't apply here. Yes if Iran launched a nuke at Israel, or vice versa, and the other had nuclear capabilities, they would destroy each other, but the MAD scenario between the USSR and the United States doesn't really play out here.
The biggest global risk in this case would be that tactical nukes would be back on the menu which would immediately change the face of modern warfare.
So the reason to make an exception to the Non-Proliferation Treaty just for the giant tyrannical fundamentalist state is, what, because otherwise they might get insecure and anxious?
Ted Cruz is explicitly advocating that Christians are biblically commanded to defend the modern day state of Israel, and that this alone justifies our attack on Iran.
Ted Cruz can blather whatever he wants (and he also footnoted it to say it was only HIS belief), but only Iran has holy-text justification for the destruction of all Jews, mentioned numerous times in authenticated Hadiths (just search them for "The last hour will not come")
In the past 24 hours alone, all 3 parties in this conflict have attributed their success to God. You genuinely, honestly have to be more specific in your comment because not a single involved participant is a fully secular country.
So, with that being said - which nuclear-obsessive theocracy do you support?
israel's whole existance is based on the idea that they are gods chosen people and god promised them that land, and they must defend it or it dishonors him.
going by project 2025, theres a very significant and influential portion of the american conservative sphere that is pants on head evangelical. and the idea of supporting israel as their christian duty is a huge part of that
lets not pretend this isnt the crusades with nukes. all parties here are operating on barbaric political principles
one of the scariest parts of the current US administration is that there is a fairly strong evangelical Christian belief that a massive (possibly nuclear) war in Israel is a necessary precursor to the 2nd coming.
