By retaliating against Hezbollah the Israelis warned them that they can expect that conquering Eretz Yisrael will NOT be a push over, and they did so in a way that minimized non-combatant casualties (how many people give their work pager as a toy for their kids to play with?). Report indicate that the injuries were from the pager exploding in the hand and near the face of the user, or in their pockets. If a thief and murderer can break into your house, do his will, and leave without fear of consequences, he’ll continue to do so. Seriously wounding a large part of the enemy’s armed forces is in fact a much more effect measure than levelling the houses of the civilian population.
Calling Hezbollah a “terrorist” organization is a mistake. It is a formal armed force that is under Iran’s de facto command. They are no more terrorists the Israeli artillery or air force units – the only difference is Hezbollah primarily targets civilians, which is illegal under international law and that fact should help us understand that the pro-Hezbollah (and pro-Hamas) movements worldwide are criminals similar to the National Socialists and allied parties in Europe in the early 1940s (and yes, I’m suggesting that the pro-Palestinian demonstrators and politicians, including most of the “Progressive” wing of the Democrats, are NAZIs, pure and simple). And we need to remember that successful deNazification involved inflicting mass destruction and executing the leaders.
