TL;DR Israel's peace offers are not "generous" as often described, and they involve significant concessions that undermine the idea of a sovereign Palestinian state. The article reviews the Camp David negotiations from 2000:
- The offer effectively annexed 10% of the West Bank to Israel, with an additional 8-12% remaining under "temporary" Israeli control.
- In return Palestine gets 1% of desert near the Gaza strip.
- Israel demanded control over Palestinian airspace, 3 permanent bases in the West Bank, presence at Palestinian border crossings (presumably this references border crossings to other countries) and "security arrangements" at the Jordan border which required more territory.
- Israel was also allowed to invade at any point in case of "emergency", with no definition of what an emergency is.
- In East Jerusalem, Palestine's proposed capital city, Israel refused sovereignty over Palestinian neighbourhoods.
- Israel would only allow a very limited return of a very limited number of refugees over a very long period of time.
In general, the article claims that Israel's peace offer with the establishment of a Palestinian state was not actually granting sovereignty to that state, and instead sought to legitimise the Israeli occupation.
