One of my first posts on this thread was saying that the Arab coalition needs to get aggressive with the US as far as diplomatic options. Remove US ambassadors out of all their states and ask the US to pressure Israel to not only stop the disproportional use of force, but to make Israel stop the home destructions and evictions and ethnic cleansing and steeling of Palestinian homes in Jerusalem and the WB. They haven't done that, and the only entity trying to stop the escalation is Egypt sending delegations to both, Israel and Hamas and despite being rejected at first, they're continuing their efforts. So interestingly enough, we are somewhat on the same page.
Just counting populations vs a small one with the backing of the greatest superpower and all the entanglements in between complicate and exacerbate the matter a lot more than you or I would think.
