Iran has been the biggest force standing for the Palestinians. Other Islamic or Arabic nations have failed to protect and speak for the oppressed people of Palestine. Some of these nations are allies to these oppressors and don't want a sour diplomatic relationship. The pressure on these invaders to leave Palestine is coming from Iranian-backed organizations. Israel, the US and its allies see Iran as the only impediment to the destruction of Palestine. The war will never end until the Palestinians become free and all their lands reclaimed.
