The “right of return” is not actually a “right,” especially if you are the party who started the war and then lost it, as took place in 1948.
The “right of return” is, rather, a demand: that all the Palestinians who fled their homes during the war of 1948 – and all their descendants – be allowed to return to what is currently the State of Israel.
Thousands of wealthy Arabs left their homes in anticipation of a war, thousands more responded to Arab leaders’ calls to get out of the way of the advancing Arab armies. A handful were expelled, but most simply fled to avoid being caught in the crossfire as the Arabs waged war in response to the establishment of Israel.
“There is a limit to how far Abbas should go to appease Israel.” — Saudi commentator, mepc.org, 2012.
[A]n extensive letter to Abbas, signed by 78 Palestinian organizations, contained a semi-veiled death threat.
It has now become clear that when Abbas says he supports the two-state solution, he is actually talking about one Palestinian state in the West Bank, Gaza Strip and east Jerusalem, and another one that would replace Israel.
In Israel, there are currently about seven million Jews and two million Arabs. An influx of untold millions of Palestinians would mean, literally, the end of Israel. This appears to be exactly what Abbas and other Palestinians are hoping to achieve.
In pursuing this hardline push for the “right of return,” Abbas desires a two-state solution: two Palestinian states, one in the West Bank and Gaza, and the other in all of Israel.
[Abbas’s] time is running out and his people are thoroughly angered and disappointed by his lack of tangible results, either in displacing Israel or in bettering their lives.
Addressing Abbas, the comment reads: “We, the Palestinian people, Mahmoud Abbas, want all of Palestine… 67 and 48, all the land, water, sky, air… and the Jews do not exist with us…. Let history write your name. You admitted that the negotiations with the Zionists were a mistake and a sin… Mr. President. Safed is home and you want to go back to your country…Palestine has tens of millions of owners of the land, and you have been repeating the same mistake for 20 years. The Palestinian people, are tens of millions. We will return. We will expel them [Jews] and displace them. Even their graves, Mr. President, will not remain under our soil… we will kill them.”
