A statement from the Satmar Rav, Grand Rabbi Joel Teitelbaum concerning the so called "Yom Ha'Atzmau't" (Zionist "Israel Independence Day")
We must not minimize the seriousness of the grave sin of rejoicing or appearing to rejoice and making a festival on the terrible Day of Blasphemy that they call "Yom Ha'Atzmau't. The day that the members of the conspiracy against G-d and his Messiah, established their Kingdom of Atheism over the Jewish People, by uprooting the Holy Torah and the Faith, at that time the shedding of blood of myriads upon myriads of Jews began.
This is much worse than accepting idolatry because they not only accept it but celebrate and rejoice in the terrible rebellion against G-d and His Holy Torah.
There are many sinners and even deniers of the Faith whose hearts trouble them because they are not serving G-d, but they are unable to stand up against temptation and against deceitful ideologies that confuse them. However, those who rejoice in this sin are guilty of much worse blasphemy.
May the Merciful save us from them and from their followers, and strengthen our hearts and enlighten our eyes in His Torah and in His Service.
May His name be blessed.
