A fair portion of the western world's response to this seems to be somewhat confused.
It's almost as if they've forgotten their own governments spent over two decades engaged in a "war on terror" in the Middle East during which, they laid seige to entire countries, reduced whole cities to rubble, abducted innocent people for 'interrogation', and killed almost countless civilians.
All this was apparently justified in their eyes to combat the threat of Islamic extremists. Islamic extremists who lived thousands of miles from western borders but who posed a mortal threat to western ideals none the less.
Yet now, when Israel fight the same threat literally on their door step, the same people who supported battling Al Qaeda, the Taliban, ISIS, etc., to the death denounce Israel as monsters and expect them to open their lands to terrorists who have vowed to obliterate them.
Many would have you believe the Palestinians, to a person, are helpless with no agency of their own and ignore the fact that many (some surveys and commentators suggest the majority) support Hamas in their actions, certainly they voted them into power when last afforded the opportunity.
Whether that is true or not Palestinians are no more or less helpless than the Afgans, Iraqis, Syrians, or Libyans were, yet that didn't stop us from launching waves of shock and awe bombing campaigns and launching full-scale invasions to combat our terror threat.
The double standards applied to Israel are mind-boggling.
