The Irgun was targeting many things, they were of course ingrates who hated the Brits that had gifted their own colonial land to these frauds for free, but they were also conducting terroristic operations against arabs. It's all very simple really, Israel was doing tactics that were morally acceptable in the 1800s but had fallen out of fashion by mid 19th century. It's vety simple, just answer this. Where are the upto 3 to 4 previous generations of most current Israelis from. Are they from the Levant or are they from Europe? And if Europe, did they migrate peacefully to an existing country or take over lands someone else was living in?
