The british soldier was killed on a british street. The two israeli reservistswere killed well inside the occupied west-bank. Also the two israeli reservist wore civilian clothes, which at the time were seen by most palestinians as the "uniform" of israeli assasination squads working undercover.. So all in all entirely different scenarios, and a comparison that is disrespectful to the slain british soldier.
