The reason not many Muslim nations have intervened to protect Israel from Muslim terror and threats is probably because Muslim nations feel vulnerable. They probably fear that, like the Jews, they too could be persecuted and obliterated either culturally, though oppressive assimilation politics, or even subject to military attack in the name of democracy. As Israel is the West's ally in the Middle East, it has born the brunt because it is the center of liberal democracy in the Middle East. I could be completely wrong, but that is what it seems to me could be the root problem. However, Muslim countries might recently have become more accepting of the idea of liberal democracy. Yet, who knows - why should they? They could be regarded in the same way that eg, the massive size Amish exclusive communities in the US are regarded and accepted by mainstream America. Moreover, citizens of Muslim Middle East countries are probably able to emigrate to eg, the US, if they would prefer to live in such an ultra-liberal country.
