I think progressives never thought about this because we banked on immigration and demographic change allowing us to win culturally and electorally but the issue is immigrants tend to be overwhelmingly male, that is how Trump won actually he won over a lot of Hispanic,Black,Asian and indigenous men who feel humiliated by a new culture, economy and world.
So what can we do rhetorically and policy wise to win more young men over ?
Iran getting nuclear weapons means the USA is very much involved - not by their own choice - no matter what you might think, because Iran has been extremely “death to the USA” for the longest time. Why do you think they’re trying to make nukes?
The USA, as the global military super power, is the de facto “peace keeper through military might” when it comes to countries escalating like this (by building nuclear weapons).
