A people need a defined territory to declare statehood.
Those are rights and duties of states, not about declaring statehood.
Also, all the land inside the green line is Israels defined territory.
Not so.
2. The Armistice Demarcation Line is not to be construed in any sense as a political or territorial boundary,...
The Avalon Project : Egyptian-Israeli General Armistice Agreement, February 24, 1949
The armistice lines specifically
do not define territory.
Tinny, the only terms you (and those who think like you) will accept is the leftmost (100%) map at far left in the image, below...
You can't have it.
Either you (metaphorically, your side) face Reality and compromise, or lose it all.
That is a choice that has been facing you for 66 years.
And you have been making the wrong choice for those past 66 years, and continue to do so, today.
Comes a time, when the stakeholder who controls the land, grows sufficiently weary of the intransigence, and moves to break the long-running and impossible deadlock, by opting to CUT the Gordian Knot, giving up on trying to un-tie it.
The way for the Israelis to CUT the Gordian Knot are to either (1) slaughter the Palestinians or (2) kick them out and send them packing across the borders of Jordan and Lebanon, never to return.
Unlike the Palestinians, sworn to drown the Jews in the Mediterranean, the Israelis, as a People, are far too humane to opt for (1), so they'll probably settle for (2), if you push them far enough.
Which is just about where they are now, in contemplating that Gordian Knot that you insist on presenting them with.
With people like you in charge (and that's what Hamas is, in this metaphorical sense), Israel has no other choice, if it is to survive, and have defensible borders that will sustain them over the coming centuries and generations.
And, I assure you, they do intend to survive.
Option (1) is unacceptable, but they'll probably get away with (2) if it's done right; there is certainly adequate precedent for such population transfers in modern history.
Your (your side's) intransigence is what is pushing Israel towards just such an answer; even though it will cause them some trouble, for a while, afterwards.
Better a few years of censure than extermination.
Keep it up... you're (your side) ruining whatever tiny chance that might otherwise still exist for a reasonable compromise, and you're condemning the Palestinians to Eviction and Expulsion - mostly because you don't believe it can happen, and are stupidly pressing your luck with that delusion firmly entrenched in your minds.
The warning signs are there, but you (your side) are wearing blinkers, and cannot see them, or will not heed them.
And, when the day comes that you must face the consequences of such blindness - and that day is probably closer than any of you imagine - then, the world (beyond the realm of Islam, anyway) will not help you to remedy your stupidity, and you will be scattered, and absorbed and assimilated into the surrounding region, and be quickly forgotten.
Nature will have de-selected you.
Such is the fate of blind fools.
