In 1948 eight Arab countries declares war on Israel after Israel accepted the UN partition plan and called, in her declaration of independence (from Britain) for a peaceful together with her neighbours.
Between 1948 and 1967 those same Arab countries continually attacked and sponsored attacks against Israel while Israel.
In 1967 Egypt, Jordan and Syria finally lost Sinai, Gaza, the West-Bank and the Golan heights to Israel.
Israel immediately offered to return those lands in exchange for peace. The Arab countries met in Khartoum and formulated the so-called "Three Noes": no peace with Israel, no recognition of Israel, no negotiations with Israel.
Between 1968 and 1979 Egypt and Syria attacked Israel twice more, once on Judaism's most holy day.
In 1979 Egypt agrees to peace and Israel returns Sinai as proposed by Israel in 1967.
Between 1979 and 1994 the "Palestine Liberation Organisation" fights a war against Israel's civilian population.
In 1994 the PLO agrees to peace and autonomy for Gaza and the West-Bank outside Jerusalem.
In 2000 the PLO breaks the peace agreement.
And in 2010 the Guardian published an article that asks whether "Palestinians" can trust the Israeli prime minister given "17 years of disappointment" for the "Palestinians", a constant Israeli "no", and refers to a supposed "nugget of conventional wisdom [that[ holds that while the Palestinians want a deal but not negotiations, the Israelis want negotiations but not a deal."

I assume it goes without saying that the commenters, who are obviously not anti-Semites, do not trust a Jew to keep a peace treaty even if he claimed to want one based on, presumably, Israel's history of proposing peace treaties and keeping them.
It doesn't matter how often Israel proposes peace or how often the Arabs reject even negotiations or the recognition of Israel's existence (most Arab countries still don't recognise Israel's existence) or how often they break peace treaties, it will remain, according to western media, Israel's fault and Israel's duty to keep peace negotiations going.
Just once I want to read an article written by a western liberal that, while obviously blaming Israel for everything that ever went wrong in the Middle-East, would at least mention, perhaps just as a foot note, that it was the PLO who in 2000 broke the peace treaty that that is at least part of the reason why there is no peace now.
(I am sure none of those writers will ever even mention the rejection of peace by the Arabs in 1948 and 1967 or the three noes of Khartoum.)
