What is our proper response when we hear about such attacks?

When attacks occur, stop obsessing over news. Immediately turn to HaKadosh Baruch Hu and His Torah; these are Hashem's calls for genuine teshuva. This means daily Torah learning, living by it, and improving personal Avodat Hashem: honesty, proper Shabbat, guarding eyes, and refining character. Disregard all distractions—fake news, political correctness—and focus solely on Hashem, His Torah, and true sages. Educate fellow Jews on tikkun habrit, Shabbat, and middot. Rebuke sin: privately for private acts, publicly for public desecration. Intensify prayer, real teshuva, and tzedakah. Speak the uncompromised truth of Torah, including reward and punishment. This path brings protection, salvation, and peace.
