Russia’s invasion didn’t help, but hasn’t seemed to trigger major proliferation concerns. In particular, Ukraine has no given any indication of pursuing nuclear development as a result. Indeed, doing so would put their much needed military aid at risk. All indications is that other countries that feel threatened by Russia are making similar calculations.

In contrast, Iran pursuing a nuclear strategy is very much on the table. We’ve established that their ability for conventional self defense is woefully inadequate; their proxy network has been severely degraded; and their prospect for a diplomatic solution has been repeatedly undermined.

If Iran does get nukes, that could be a catalyst for others in the region to do so as well.

Because ethnonationalism is a coherent ideology.

I’m don’t know any ultra-Orthodox but do have several friends/family that keep kosher, and all of them are satisfied with just keeping two sets of dishes (although some just have one set and are satisfied that washing them count).

The disposable dishes, cooking in foil, and such comes up when they visit someone like me who does not maintain a kosher kitchen (and even then, only one family actualy cares enough; but, as I said, they are not ultra Orthodox)
