When we see violence and hatred directed at those who appear to support Israel or the Jewish people, how should Orthodox Jews respond - through political action or through teshuva and increased Torah observance?

The only effective response to anti-Semitism is teshuva and increased Torah observance. Political action, news, and protests are useless distractions; anti-Semitism is a divine call to repentance. Instead of worldly pursuits, dedicate yourself to prayer, Torah study, and sharing its wisdom—these are our sole defense and path to divine protection.
