Can’t say I can recall the last time I heard about Jewish extremists plotting terrorist attacks abroad. The sooner Islam becomes the acceptable modern neutered version of religion, the better.
You have heard of this, though. It’s called the IDF - specifically, the nationalist/Zionist factions within it. Neighboring countries count as “abroad”.
Edit:
I’m not attempting to be an apologist for any of the sides involved in this clusterfuck. If you take exception to my description of Israel and the IDF’s actions now and in many historical cases as what effectively amounts to apartheid as a state institution at best, then I suggest you do a LOT more research on the history of the region. To be fair, the Arab countries neighboring Israel came out of the gates HOT in 1948… but that also wasn’t really the beginning of the conflict - it was just the continuation of a very old one. The history of the region did not start when the UK and the UN just redrew the lines on the map in 1948 to give holocaust survivors a country of their own (I’m being reductive, but that’s more or less what it accomplished).
At the end of the day, the governments and non-state actors in the region have had various problems with each other for a long damn time, and however you want to frame any past or current conflict, it’s always the civilians who lose.
