The four maps shown by Kendoiwan aren't accurate. They are deliberately misleading, because they compare what can't be compared.
Only the two in the middle have some meaning.
The first one is an ethnic chart, while the three remaining ones are political borders. And that's not the same thing at all, since a lot of Arabs remained or returned in Israel in the meantime. And for instance, the Bedu tribes of the Negev sided with Israel in 1947, hence they are shown in white "after"; while they were shown in green "before".
At last, the fourth map is totally inaccurate, since as Lowtech Redneck already pointed, what Barak offered during the Taba talks was very different; and still, it was rejected mainly because the question of the Right of Return of Palestinian refugees couldn't be solved (Arafat and Qorei adamantly refused to settle the question).
Later on, these offers would lead to the Geneva Initiative, and even if it's not an official proposal, I think it's a interesting step towards peace, if it could ever be achieved.
Furthermore, the website that hosts these maps is known to be severely racist and Anti-Semitic, hence the presence of people like Israel Shamir and Thierry Meyssan amongst its writers (and various other neo-nazis and Holocaust deniers). Let's say this source is not reliable, very extreme, and hence, the result is quite predictable.
I know Kendoiwan likes conspiracy theories, but here, frankly, it smells very bad.
