So if every Hamas fighter is killed, no Palestinian will be angry about being dispossessed, cities and homes destroyed, and will simply shrug off dead children and noncombatants by the thousands as 'bygones?'
Not thinking that is how it will work out.
The Palestinians are trying to use the same line my uncles and many others heard from German civilians in the 1940s. "We didn't know the camps existed" wasn't believable then and it's not believable now. Sorry, I don't believe that none of the "innocent" civilians saw the preparation work for this terrorist attack.
