You are absolutely right but you misread the Muslim mind. If any country, other than Israel, were to invade Gaza and kill every living soul there, no Arab country would make a peep. Look at China and the Uighurs or Myanmar and the Rohingya or the inter-Muslim wars where Hundreds of thousands have been killed. How many UN Resolutions has the Arab League proposed? One each and then silence.
Islam is a death cult masked as a religion. Islam keeps its status through brainwashing and forceful violence. Violence being the operative word.
They are also equal opportunity haters and will only join each other when religion is involved. The reason for that is the brainwashing of martyrdom. They will kill each other to be martyrs or the other for the same reason.
