How did Morocco respond to the International Court of Justice ruling on Western Sahara in 1975?

Despite the ICJ ruling that the Sahrawi people were entitled to self-determination, Morocco's monarchy immediately defied the decision. King Hassan II took to national TV and radio, calling for hundreds of thousands of volunteers to march into Spanish Sahara. In November 1975, approximately 350,000 unarmed Moroccan settlers crossed the border in what became known as the Green March. This aggressive action took advantage of Spain's political instability, as dictator Francisco Franco was in a coma. The Moroccan invasion effectively attempted to colonize and claim the territory despite international law upholding the Sahrawi people's right to determine their own future.
