With your upbringing in a polarized environment, I am afraid you portray it on every aspect of life, even politics. In your mind resides an ideology which is deeply rooted in allegiances. If someone aligns with the Imam (ra), for example, he or she is an angel short of infallibility and if someone even disagrees with the Imam (ra), even if he or she is correct, the lowest place in Hell is reserved for him or her. Your present-day concept of Nawaasib is Israel, a country which, undoubtedly, we all hate. An aggressive, racist force which has mastered the art of land grabbing and shedding innocent blood. And your present-day makeshift Imam (so to speak) is the Shia alliance, headed by Iran which (I think) isn't necessarily a bad thing; I am always for people uniting so long as their unity isn't toxic to those around them. Therefore, when you do not see an outwardly celebration of Israeli loss, you misconstrue it as "not being happy" and you see it as an insult to your present-day makeshift Imam while completely ignoring the underlying factors.
I do not know how old you are but I was a teenager during the Israel-Lebanon war of 2006. I stood in a blistering hot August day outside the White House with Palestinian and Lebanese flags condemning the actions of Israel. A week prior, I had stood in front of the house of the Israeli Ambassador. And then in December 2008, on a cold rainy/icing morning (during the Gaza offensive or Operation Cast Lead). And again...and again! More times than I can remember!
As for this news, it brings joy to my heart. No sovereign country should have its air space violated and civilians killed by a neighboring country, an illegitimate one at that!
