Who knows? Maybe the only people who can speak with authority on this issue are the Palestinian equivalent of our Supreme Court Justices, and they haven't yet accepted a case in which they would make that ruling.
Oh, come on now. No ruling is needed. Prove the charter is changed, collect $1 million. If it really was changed it should be pretty easy for them to do.
No, it's not that simple. Without an authoritative ruling on what steps are necessary to effect an actual change in the Charter, there's no way to determine if the steps already taken are sufficient.
That guy's money is safe, not because it's certain that the Charter remains unchanged, but because you have to know what constitutes proof before you can know if you have it.
(That guy's challenge reminds me of the question of
whether the Sixteenth Amendment was properly ratified, and whether an income tax can be levied on other means of earning money, such as exchanging labor for pay. I bet you a million dollars you can't prove it either way but you still have to pay Income Tax on your wages.

Who cares, anyway? It's just another sideshow excuse for Israel to not recognize the Palestinians' right to live in Palestine and participate in their government.
The point is that you made a claim which is obviously wrong. How credible should we find the rest of your observations about what you read?
I said:
And why should Israel recognize a government that refuses to recognize Israel?
The Palestinian government recognized the government of Israel, that government's right to negotiate borders, security, and related issues, and most importantly Israel's right to exist as part of the Oslo Accords. Now it's time for Israel to reciprocate by recognizing the State of Palestine's government, right to negotiate borders, security, and related issues, and most importantly the State of Palestine's right to exist, too.
You responded with the usual ahistorical quibbling and distractions from the point: it's time for Israel acknowledge the right of the Palestinian State to exist in peace and security, in the same way the Palestinians have publicly acknowledged Israel's rights to the same things, and stop moving the goalposts.
You might feel that the Palestinians haven't fully or genuinely recognized Israel, but that's a side issue. The Israelis can use the same words the Palestinians used and effect the same degree of actual change if you'd like. The important thing is that they say the words out loud where people can hear them just as the PLO did, and do for the Palestinians what they demanded the Palestinians do for them back in the 1990s.
As for my observations about what I read, if you disagree with my observations we can discuss it, but only
after you've read the source material. No bullshitting allowed. No assertions the author was biased, or the article was inaccurate, or the clause doesn't mean what the quoted portion says if you haven't even read the material or checked out the claims yourself.
The point is this: the Palestinians made public statements in which they recognized Israel's right to exist, and it's time for the Israelis to reciprocate by making public statements in which they recognize the right of the Palestinian State to exist, too. Amending Charters and Basic Law for sure and for certain can wait until both parties publicly declare their mutual acceptance.
Israel has offered reasonable peace deals--that's pretty clearly an acceptance of a Palestinian state. The deals were rejected without even a counter-offer because the talks have just been a sham from the start--it's just an exercise in getting concessions. Since Israel isn't going to agree to more front-loaded deals there's no point in the Palestinians making a deal anymore. The game now is to demand concessions in exchange for talks.
Which Israeli offered peace deal accepted the existence of a Palestinian State? Name it, so we can read it.
