The only way our of the conflict is for the palestinians to accept defeat. You lost, get on with your life with what is left of your land and have your own state so you can finally live in peace. You were screwed up and cheated by a much more powerful nation, supported by much more other powerful nations. It is nice to fight for your rights but it is unwise in a war you cannot win and will lead to only more suffering and the inevitable final result which is Israel fully taking the west bank and Jerusalem. It is like Mexico trying to take California back.

Sad truth is, unless the palestinians accept defeat, they will just live in suffering and misery until they are fully assimilated and their territory taken.
Israel is a major military nation with the full support from the west, they can obliterate Gaza and the west bank anytime they want, they just dont do it because that would paint them, maybe as the bad guys for the whole world for all eternity.

Personally I also think Gaza is a problem that cannot be solved, because it will be part of the Palestinian State but it is separated physically from the West Bank, with Israeli territory in the middle. So the best approach would be to move Gaza's population to the west bank or even better, Israel could concede some of it's territory to the north to the palestinians so they could have an opening to the sea as a compensation for giving Gaza to Israel. The international community could help with the fund to move the population and building the necessary infrastructure. This way the Palestinian State would have an opening to the sea and would have it's territory consolidated.

But it is too complicated and will never happen.

Israel has implemented ethnic cleansing in Palestina for decades. Only now is getting expossed to the general public. It has done so both by killing and, more frecuently, by expelling palestinians from their homes and clearing palestinian lands in order to create jewish settlements. The violence we witness today started precisely when Israel forces tried to expel palestinian families from their homes in Jerusalen and use that land to create jewish settlements (As it has been doing for years now... Only that this time palestinians fought back fiercely). Zionists invaded and occupied Palestine in 1948, used terrorism to expel the colonial power there (the british), killed and displaced millions of palestinians, took their properties and homes and stablished the State of Israel. They did so backed by the resources of multimillionaires like the Rotchild and the Rockefeller families. And by the US, which needed a powerful ally in the area in order to secure its geopolitical and material interests. The palestinians have since suffered the stealth of their land and their country and the humilliation of being pointed as the "bad guy" while being the victims. Israel asphixiates the palestinian economy both by blocking Gaza and Cisjordania and by directly destroying the means of life of the palestinians (I.E., allowing israely settlers to cut thousands of olive trees wich provide palestinian families their only way of income). It's clearly an ethnic cleasing geared towards phisical elimination of palestinians from their land (and by phisical I mean no necesarily killing them, but making them dissapear from the land by terror, displazement, harassment, etc., in order to allow Israel to dominate the whole land that was once known as Palestine).
