Better get a better history book, yours is very distorted. "What about numerous bombings of buses, bus stations, markets and other civilian targets by the Irgun?" What bus or bus station, nor were markets ever targetted by Israelis. The Arabs were the ones doing the bombings, try again. The Stern Gang did commit offenses that are terrorism, there is no proof that Irgun did so. "Your knowledge seems as one-sided as his." Yours is quite incorrect so, you may need a refresher course.
