Its been answered you just don't have the intellectual capacity to see the answer.
But if i break it down in simple terms. Palestine cannot achieve anything on her own, she failed too many times in the past 100 years to think she can dictate her fate.
What they should be doing is basically as much as possible to avert things like what's happening now. They have to endure and persevere for as long as possible in the hope that outside help will arrive one day. Ataturk once creating Turkey seeing that Cyprus with its Turkish Muslim population had been annexed by the British told the Turkish Cypriots to hold tight, to stay on the island and to endure, one day when Turkey has the strength, Turkey will come. That arrival came in 1974 about 35 years after Ataturks death. The Turkish Cypriots were also facing a genocide and unlike the Palestinians nearly the entire muslim world was silent and many arab states were helping the greeks like egypt and syria. But the Cypriot Turks endured and the their Turkish brothers came. Today the north is peaceful, cypriots Turks don't go to bed fearing whether they will wake up in morning.
So stage one, endure do everything to avoid giving the zionists the excuses they want to use to come and crush you. I have no doubts that oct 7th made the zionists exceptionally happy and excited.
Stage two is for someone else to come and help. No one will come and help if the common Muslim remains ignorant and arrogant. The common Muslim has to educate himself and he has to create pressure on his government to act. This is the only solution now. Most states are corrupt with charlatans in charge, they will do nothing unless the people themselves force the issue.
Let me give you an example of pressure people can create. The Russians not so long ago bombed our troops and killed about 40 of them. The AK party government did everything to hide it from the people. The news didnt cover it, none of the politicians wanted to talk about it. But the incident spread like wild fire across social media, the Turkish nation was angry that wanted war against Russia. People even pensioners were rushing to the syrian border demanding to be given a gun to go and kill the Russians and their assadist lackeys. This forced erdogan to move, without this pressure he would have done nothing. But public pressure led this.
The solution is the common Muslim must create pressure on his governments. Turks supported AK party but they have completely failed Palestine, don't vote for them again. The next government who comes in seeing this will know in the same circumstances he will have to act if he wants to remain in power.
Now i could write a thousand pages on all the different things that could be done at a macro and micro level, but truth be told it would be wasted here.
On a side note your country has a population of 300 million people, instead of arrogantly asking me for the solution why doesn't your country find a solution? This isn't to attack you but its to highlight a point, no Muslim majority countries governments feel any real societal pressure to do anything. That blame has to rest on the people.
In Islam we are taught to do according to our means, the truth is most of us are really doing nothing.
