The deligitimizers of Israel are now launching an attack on Israel's legal system. Not on the IDF, not on settlements, but on the world-class legal system inside Israel. The reason has to do with Israel's withdrawal to the internationally recognized border with Gaza, in 2005.
The 1990s tested the proposition that if Israel recognized the Palestinians and negotiated with them towards a mutually acceptable partition, this would lead to peace. Well, that didn't work, did it.
The Naughts (is that what they were?) tested the proposition that if Israel unilaterally moved back to internationally recognized borders facing Lebanon and Gaza, this would bolster Israel's legitimacy, undermine allegations about its colonial and aggressive policies, garner it international good will and generally strengthen its position. Well, that didn't work, did it.
Rational people generally accept the proposition about causes and effects, measurable means of testing, and accepting their results. Non rational actors wave away all uncomfortable results, invent ways to explain them away even if they contradict previous assumptions, and stick to their positions regardless of facts. I try to be rational, but maybe that's just me.
