Even as someone asking for fairness to Palestinians, I have to somewhat agree that Arab states are somewhat cynically using the Palestinian plight to feather their own nests. And to blunt any calls for internal reforms, those Arab leaders can point to the Palestinians and say, are you not glad that you live here and not there where things are ever so much worse.
But with an estimated 1.4 billion in damage to Gaza, Arab governments and private charities seem ready to pony up the cash, and as a likely result, a flood of supplies and material will go to Gaza through various routes. Making detection of smuggled in arms and weapons more difficult for Israel. And somewhat the real question will become, if at some point in time, Hamas or other groups inside of Gaza start again firing missiles into Israel, will the larger Arab world repeat its mistake of leaving Gaza toothless? As we saw in the three year ago Israeli incursion into Lebanon, Hezbollah had some rather effective weapons able to damage and disable State of the arts Israeli tanks and the training to use them. But when Israel moved its tanks into Gaza in its recent offensive, Hamas had nothing to fight tanks with.
Only time will tell.
