Facts are facts, First of all, the Palestinians did NOT attack Israel first in 1967. The contrary is correct.
The Six-Day War fought between June 5 and 10, 1967, by Israel and the neighboring states of Egypt , Jordan, and Syria. After a period of high tension between Israel and its neighbors, [b]the war began on June 5 with Israel launching surprise air strikes against Arab forces.
Let's look at the period of "high tension":
May 15: President Nasser of Egypt ordered two armored divisions into the Sinai Peninsula.
May 17: Nasser ordered UNEF, the UN force in the Sinai, to depart from Egyptian territory. Three Egyptian divisions and 600 tanks then deployed in the Sinai.
May 22: Nasser announced the closure of the Straits of Tiran to Israeli shipping, cutting off all shipping to Israel’s port of Eilat. which was responsible for 30% of israel's exports.
Nasser's move was also illegal. As part of the post-1956 war settlement, the Gulf of Aqaba had been declared by maritime nations in 1957 as an international waterway.
May 25: Nasser, in a speech to the Egyptian National Assembly, said: "The problem presently before the Arab countries is not whether the port of Eilat should be blockaded or how to blockade it -
but how to totally exterminate the State of Israel for all time."May 30: Mutual defense pact signed between Egypt, Jordan and Syria.
But, you're right: Israel did strike first. What a bunch of warmongers! Why would a peace-loving state ever take seriously an extermination threat from a neighboring state and its Soviet-armed allies?
