People dramatize with talk of genocide over nuclear weapons too much. Perhaps it's good they do, we don't want to walk into a genocidal war by mistake. But I do not see any happening. I do believe that conventional wars can be fought without escalating to nuclear. We already saw that between nuclear and non-nuclear armed countries, and between nuclear-armed countries.
Incidentally, that is a more immediate and realistic damage than most people realize. Here in Europe where I live I'm happy to stay put on the far western end of it...
Specifically regarding Israel and Iran, the threat is the economic and social damage that a conventional war will do to both countries. Iran would probably survive unmodified, Israel would have its best able jewish population give up and flee, reach breaking point. They know they have a demographic time bomb ticking away. That's how I understand @Absolution
's comment. But he should be the one saying what it means.
I think that it is too far-sighted to speculate that Iran will be involved in the destruction of Israel, as now it does not seem near at all.
In fact, I think that the Islamic Revolution is still way more endagered than the Zionist movement.
My worries are mainly cultural.
The elections themselves are not much more than a heavy reminder of a process that is known to have been happening for some time now, and is still far from being complete.
It is that dumb and primitive people are taking over as the majority culture of Jews in Israel.
I hate them and I don't want to belong to their nation.
A sense of alienation towards even my physical environment has taken over me in the day or two after the results were published. Along with a greater motivation to leave.
A confusion about how I view places that are home to me and in which I grew up. They haven't change. These specific places haven't even changed culturally. But these were gloomy days.
I don't know how it is going to affect my relationship with the state in the long term.
Anyway I didn't prefer to live here most of my upcoming years, but as said before, the motivation to leave grew larger.
And I hear this from many people around me.
Let those dumb and primitive have their own nation without us, let them become just another stupid Middle Eastern country. This is not what we and our past generations have worked hard to build.
There is no reason to lie to ourselves that we should and can live together with them as part of a single nation.
If we want to go into practics, then there is one interesting point which bothers me over the excpected change of governments. It is that during the reign of the recent government, Environmentalism was politicised for the first time. By the opposition, of course.
Good reforms concerning single use plastics were exectued by the current anti-Bibi government.
Haredim (ultra orthodox jews) view these reforms as deliberate attempts to worsen their lifestyle (which for some reason includes great dependency on single-use plastic) by a malicious finance minister. The Haredi political leaders sworn to cancel the reforms, and now they were given the power to do so.
For the first time in my memory, political parties go anti-environmental, and that's only because some environmental reforms were done by their rival government.
I hope it will not create resent towards other issues, most importantly a transition towards more solar energy dependency.
