I'd say more of a rogue state: international sponsor of terrorism, authoritatian apartheid state severely limiting human rights, etc. It is not isolated in its existence and actually has support of many other states, mostly western.
well they can't be a rogue state because the 
backs them, and I don't think they qualify as pariah because 
Rogue because they do extra d6 damage every two levels when they backstab people or flank them.
I think defining it in such terns is not as important as to understand what is happening. First of all, Israel was created forcefully uppon Arab land with little justification for such, the issue is, how a country comes to be has little to do wirh the role it plays in the international cheeseboard. What counts is how international community sees it, and throughout the decades Israel is been recognized as a bona fide normal country. As of recently it might be that some talk about parts of Israel being illegitimately taken from Palestine be circulated with some potential, but it's very likely that the international community keep seeing Israel as a regular country they'll likely put everything on Netanyahu's tab and as soon as he is out is business as usual.
But if you are concerned about what it is in reality is a colonial occupation of Palestine land, shouldn't even be a country. As for being a pariah, it has not received hardly any economic sanctions, in fact the US keeps helping it so I don't see much of a pariah quality to it. Rogue state would assume I believe to behave in discord with the international standards, and Israel is doing what the west wants, what bothers is the colossal bad press it got by their means, but the general direction is what the west wanted, so some might call what's happening now as a rogue behavior but I'd find more likely it to be considered that Netanyahu is a rogue leader instead of Israel being a rogue nation.
Don't know if I made myself very clear, but hopefully I contributed to the discussion
Absolute worst case scenario, but also probably the most likely. The thing gets put on his plate. And then they wrap him up. And say, oh, it was a one-time thing. This was not supposed to happen. This is what happens when you have a crazy right-wing person in power. And then Bibi will take the fall. And we'll just be expected that that's good enough. "Imagine if the U.S. had Trump in office. It's the same thing." The libs will say. This is why our political line needs to be anti-settler colonialism. Because it does not matter if it's Israel, if it's Australia, if it's Canada, if it's New Zealand, or if it's America. The problem is the same. Native people were genocided, their land stolen. Everything you see in Israel is just a modern version of what we did in America. Hell, what the Nazis did to the Soviets is just taken directly from what America did. Fundamental fact needs to be our political line. Because otherwise, we're never going to get the People's Republic of Turtle Island.
You did an absolutely fantastic job of talking about the nuance of the situation. Well done.
However
I would really like to know what an international cheeseboard looks like. Sounds tasty!
I'm just imagining a charcuterie board with various cheeses forming the shape of a world map. Each country is its major cheese.
