Dutch, forget about the Arabs for a moment. It's clear that you have problems with them and it just fogs your mind, even though you have some valid points about it.
Anyway, I'm not talking about money, fund, political or military aid here. Humanitarian aid. Israel is both collective punishing the whole Palestinian people for the sins of Hamas by destroying their vital facilities and infrastructures and also they are hugely restricting the Humanitarian aid to the region. For tangible things, like food, baby food, clean water, wheelchairs, medicines and medical equipment, clothing, gasoline, heating aid, hygiene stuff etc. And there are many reports that claim Israel is even messing with the little allowed aid and diminishing them behind the doors. People don't even want Israel to help them, if they were just not restricting humanitarian aid to the poor Palestinian people, there would be really really huge relief for the Palestinians. Even only the volunteers and the aid from let's say French, British or Turkish people would be more than enough for that.
As for your delusions about the Arabs vs Israel. Sorry but that's just crazy talk. The Arabs have neither the military power nor the political power to do anything against Israel. Whether they are united or not, doesn't matter. You have just no idea how comfortable and authoritative Israel is in the region. You think the Saudis can use their money against Israel, money can't do a **** when you don't have any word or any power over anyone. Let alone the blockades and the restrictions, Israel even have the authority on the most border crossings in the region.
Israel is alone just too strong for the most of the Arabs and will be enough for the all of them with a tiny bit help from his uncle. Other than the Arabs, there are only two countries in the region that can potentially compete with Israel, one is Turkey and one is Iran(doubtful), which also bears nothing but a nonsensical topic anyway, because it is only hypothetical and it would be very foolish for them to mess with Israel too.
None of it matters anyway, as long as the US continue to stand behind Israel. The US provides Israel with at least $8.5 million per day as only the military aid and that's just their routine relationships. Not to mention to the very very strong bonds between the two states both politically, financially and strategically.
Plus, it's not only the US either. Yesterday for instance, Merkel the hag woman opened her ugly mouth and supported Israel along with a pious but friendly warning that they should be more careful when killing. The other western countries did the same, more or less. So, in the very very worst scenario for Israel, you'd be just talking about the third world war if anyone in the Middle East tries to swoop on Israel. Could the Arabs take the chance for the WW3 only to get destroyed by the US and the West for the Palestine? Of course not. They wouldn't do that even for themselves! They couldn't.
And before you talk about the Hamas and human shields one more time, I don't defend neither Hamas using human shields nor Israel killing kids playing on the beaches. On the contrary, I believe Hamas is behaving very very detrimental for the Palestinians and they have behaved in that way most of the time. I'm even suspicious about them whether they are genuinely contending for the Palestinian people or not. If they are genuine, then they have just no idea how much they are hurting their own case.
And again for the last time, stop telling who should live or migrate to where or who should absorb who. The Palestinians want to live in their homelands and they deserve and have every rights to do so. Nothing can justify the oppression of Israel against them.
Anyway, let me finish with a Turkish saying. Forty cats don't come up to a lion. It so fits the situation here. United or not, the Arabs just can't cope with Israel and USA.
