Why is Germany vulnerable to the Iran war?
Germany is still recovering from the 2022 Russian gas cutoff. Its industrial base requires enormous energy inputs, and another supply disruption from the Iran-Hormuz crisis compounds existing vulnerability.
Will Germany join the war through NATO?
NATO Article 5 (collective defense) only applies if a member nation is attacked. The US initiated the Iran strikes, so Article 5 is not triggered. Germany may provide logistical but not combat support.
