Active self-defense by all necessary means.
Barzel is the foundational doctrine of Yad Barzel. It holds that the defense of Jewish lives and Jewish rights is not a matter of preference or circumstance — it is an obligation, binding and unconditional.
The word means iron. Not because iron is brutal, but because iron does not bend. It does not negotiate with the force that seeks to break it. It holds.
This principle demands that every member be prepared — physically, mentally, and spiritually — to act with full force when the protection of Jewish life requires it. Hesitation in that moment is not caution. It is failure.
Barzel does not celebrate violence. It refuses to pretend that the world does not contain those who would destroy us. It answers that reality with preparation, with strength, and with the will to use both.
