What does the speaker identify as the ultimate solution for Jewish survival and combating anti-Semitism, according to Torah principles?

The ultimate solution for Jewish survival and combating anti-Semitism is Teshuva, Torah learning, and Mitzvot, as explicitly stated in our sacred texts and proven throughout history. Anti-Semitism is a divine tool to awaken us, and secular efforts—like political lobbying, "never again" campaigns, or assimilation—are futile, wasteful, and deny the Torah's promise of divine protection. Our true defense lies solely in righteous Jewish living and commitment to Torah, enabling Hashem to nullify our enemies. This is our unique and only effective tool.
