jews kill in the name of israel. It's never about judaism as religion but as nation.
All the terrorist groups pre Israel that later formed IDF like Irgun & Lehi, and later on all the wars with all the neighboring countries, the occupation and ethnic cleansing.
Currently jews fighting for an expanding nation are the biggest cause of child death, journalist death, wars, foreign assassinations, meddling in foreign policies and propaganda, and in my speculation they are even behind ISIS and other such terrorist groups because it is in their interest. They need that enemy and looming threat over the west.
They are also behind a lot of the immigration in the west, because that is also in their nation's longterm survival's interest.
These terrorist groups weren't active pre Israel
