"since 1948, Israel has done nothing but encroach upon and steal land that belongs to the Palestinians"--

This is geopolitical blood libel. From 1948-1967 Gaza and the West Bank were occupied by Egypt and Jordan. The PLO was founded in 1964, three years before the Six Day War launched by Egypt's blockade of the Gulf of Aqaba with the slogan "the only Jews left alive after this war will be good swimmers." 3 years before Israel occupied what's now viewed as the future state of the two state solution the PLO's charter called for the elimination of the "Zionist entity."

So let's do a title search on the real estate with an old parable, the best reply to the "stolen land" myth:

“Sharon sits down with Arafat at the beginning of negotiations regarding the resolution of the conflict. Sharon requests that he be allowed to begin with a story. Arafat replies, “Of course.”

Sharon begins his story: “Years before the Israelites came to the Promised Land and settled here, Moses led them for 40 years through the desert. The Israelites began complaining that they were thirsty and, lo and behold, a miracle occurred and a stream appeared before them. They drank their fill and then decided to take advantage of the stream to do some bathing — including Moses. When Moses came out of the water, he found that all his clothing was missing.

“Who took my clothes?” Moses asked those around him.

“It was the Palestinians,” replied the Israelites — “

“Wait a minute,” objected Arafat immediately, “there were no Palestinians during the time of Moses!”

“All right,” replies Sharon, “Now that we’ve got that settled, let’s begin our negotiations.”

This is how to do a proper title search in real estate.

Mr. Dunn's American analogy map would be correct if it had the British, French and Spaniards inhabiting North America 2000 years before American Indians. Jewish sovereignty in the land of Israel map existed 1800 years before the Arab conquest in 637 CE.

Mr. Dunn's maps omit the east bank of the Jordan, which comprised 78% of mandatory Palestine. UN partition gave it all + the West Bank to Jordan. But the Arabs, as in 1937, again in 1947-49 and in the December 2000 Camp David Clinton-Barak-Arafat negotiations, Arabs said no to the partition scheme Jews said yes to. Mr. Dunn must believe that there should be no consequences from starting a war of extermination, asking for 3 do-overs in 1956, 1967 and 1973, expecting to get your own special UN refugee agency that gives permanent refugee status to multiple generations of "refugees" that your fellow Arabs refuse to absorb. This case resembles that of the West Germans did with the 8m eastern Germans from East Prussia, Silesia and the Sudetenland after 1945. Nobody utters a word anymore in their favor.

Nakba: Arab muftis ordered Arabs to leave, telling their flocks you'll soon be back after we kill all the Jews or drive them into the sea. Here's what Arab leaders said in 1948:

“This war will be a war of extermination and a momentous massacre which will be spoken of like the Mongol massacres and the Crusades.…it’s too late to talk of peaceful solutions….”The Arabs conquered the Tatars and the Crusaders and they are now ready to defeat the new enemy,” — Arab League Secretary General Abdul Rahman Azzam

Refuting the stolen land myth:

19th century Ottoman Palestine was empty and desolate after centuries of parasitic mismanage-ment by absentee effendi landlords who evicted their Arab tenants to sell to Jewish buyers and shook down small indebted landowners to sell contiguous parcels of land to them at 5x the market price.

What Mark Twain saw: “One may ride 10 miles hereabouts and not see ten humans.” “Nazareth is forlorn … Jericho the accursed lies in a moldering ruin today…“There was hardly a tree or a shrub anywhere…. [Jezreel]….not a solitary village throughout its whole extent-not for thirty miles in either direction. There are two or three small clusters of Bedouin tents, but not a single permanent habitation. One may ride ten miles hereabouts and not see ten human beings….Come to Galilee for that (solitude)… these unpeopled deserts, these rusty mounds of barrenness…We never saw a human being on the whole route….” (https://freerepublic.com/focus/fr/604628/posts)

1867: The Ottoman Sultan allows non-Muslims to buy land anywhere in the Empire but the Mecca and Medina areas. This minor change in property law opens the door to immigration by Jews wishing to return to their ancient homeland just as they begin to experience more persecution in Eastern Europe.

1857, 1859: The British Consul’s reports on Palestine in 1857 and 1859 were similar to Twain’s: “The country is in a considerable degree empty of inhabitants and therefore its greatest need is that of a body of population…The Muslims of Jerusalem do not exceed a fourth of the entire population.” (https://www.youtube.com/watch?v=3Ijyyy-Mowk, https://freerepublic.com/focus/fr/604628/posts)

1878: The Ottomans launch a resettlement policy to bring foreign Muslims to “Palestine,” mainly Algerians and Circassians. Palestinian settlement “From Time Immemorial” now dates from 70 years before Israel’s creation. But you can date it much more recently…..

The real origins of the “Palestinians”, from the British mandatory government’s 1946 survey:

https://en.wikipedia.org/wiki/Demographic_history_of_Palestine_(region)#/media/File:Survey_of_Palestine_Page_211.jpg, https://en.wikipedia.org/wiki/Demographic_history_of_Palestine_(region)

Britain’s anti-Jewish immigration policy is clear here: Trans-Jordan was the sieve through which Arabs “temporarily” entered Palestine.

Jews repeatedly accepted the two state solution Arabs rejected to "ensure that both sides have a place they can call home." But is this really feasible when one side dreams of "free Palestine from the river to the sea". Or does Mr. Dunn forget that Hamas' charter, like its PLO predecessor, calls for the elimination of the "Zionist entity" plus the extermination of its population. Calling for negotiation with Hamas is like asking the Jews of the 1943 Warsaw ghetto to negotiate with the Germans. The difference between then and now is that Jews can now defend themselves. We've learned from Mr. Dunn, Ivy League law schools and the "gas the Jews" chants in Sydney that dead Jews elicit far more sympathy than live Jews who defend themselves.

Fatah has accepted Israel's existence only provisionally. Learn the difference in Arabic between salaam--peace--and hudna--truce. Arafat signed a hudna in 1993, not salaam. How do we know? He said so:

“Since we cannot defeat Israel in war, we do this in stages. We take any and every territory that we can of Palestine, and establish a sovereignty there, and we use it as a springboard to take more. When the time comes, we can get the Arab nations to join us for the final blow against Israel.” https://medium.com/illumination-curated/palestine-israel-slogan-demolition-and-1712e39e9c1d:

At Camp David, December 23, 2000–January 2, 2001: Israel accepts and Arafat rejects the Clinton Parameters: 94–96% of contiguous territory in the West Bank and 100% of Gaza, compensated by land swaps elsewhere + an East Jerusalem Palestinian capital comprised of Arab areas with sovereignty over the Dome of the Rock. As in 1937 and 1948, same old story: Arabs say no to a Jewish yes:

“Clinton asked each side for a yes or no response by December 27th. It was made clear that a “yes” meant agreement within the Parameters and that a non-response, a maybe, or acceptance outside the Parameters would all be considered rejections. Clinton presented the Parameters as take-it-or-leave it, and if not accepted, they would all be off the table once Clinton left office on January 20, 2001.

“Arafat’s negotiating team’s) memo specifically clarified that the return the Palestinians demand is to “‘their homes,’ wherever located — not to their ‘homeland’ or to ‘historic Palestine.’” The memo further…rejected defining the new Palestinian state as “the homeland of the Palestinian people” because “this nullifies the right of return.” Finally, the memo enshrined the Palestinian rejection that a Jewish Temple ever existed: “In the first formulation regarding the Haram, accepting that the Western Wall is a part of either ‘the space sacred to Judaism’ or ‘the Holy of Holies’ will amount to implicit recognition that the Temple lies under the Haram.”

As Israel’s Foreign Minister in 1966–74, Abba Eban said, “the Arabs never miss an opportunity to miss an opportunity”. Saudi ambassador to the US, Prince Bandar, said the same thing differently to Arafat after the PLO leader lied when Bandar asked him if he’d said yes to the Clinton deal:

““I hope you remember, sir, what I told you. If we lose this opportunity, it is not going to be a tragedy. This is going to be a crime.” …”I wanted to cry, my heart was burning at how the opportunity was lost again and perhaps for the last time…”

Now let's look at who are the Palestinians. Are they a nationality separate from Egyptians, Jordanians, Lebanese, Syrians and Saudis as westerners understand nationality's meaning? The clear answer from the "Palestinians" themselves is no, absolutely not:

"1977: The Dutch newspaper Trouw publishes an interview with the PLO’s head of military operations Zahir Muhsein about the invention of “Palestine”:

“The Palestinian people does not exist. The creation of a Palestinian state is only a means for continuing our struggle against the state of Israel for our Arab unity. In reality today there is no difference between Jordanians, Palestinians, Syrians and Lebanese. Only for political and tactical reasons do we speak today about the existence of a Palestinian people, since Arab national interests demand that we posit the existence of a distinct “Palestinian people” to oppose Zionism. For tactical reasons, Jordan, which is a sovereign state with defined borders, cannot raise claims to Haifa and Jaffa, while as a Palestinian, I can

undoubtedly demand Haifa, Jaffa, Beer-Sheva and Jerusalem. However, the moment we reclaim our right to all of Palestine, we will not wait even a minute to unite Palestine and Jordan.” (http://www.indymedia.ie/article/13700)
