You sounded like you were saying that Palestinian grievances were reaching back 70 years ago. My point was that there are large numbers of Palestinians who have much more recent grievances than 70 years -- like dead relatives of all ages, or lost homes, within their lifetime. What percent of them have that, I have no idea, and I'm genuinely curious what you think the percentage is. But honestly the point wasn't needing to dig up an exact number, 4% or 20% or 50% or whatever. Any of those is too many, and you seem to define Palestinian retribution for it as "terrorism" while Israeli retribution is defined as "defense."
