In 1967, the IDF was spoiling for a fight, and was extremely confident that it would defeat the Arab armies quickly and with low losses. It had planned and trained for a first strike on Egypt, which is what it ended up executing.
The opposite thing is true: we have documentary evidence that Egypt had a plan to preemptively invade. Again: cite a book where you're getting this stuff from. In addition to WP and AskHistorians, I'm citing Benny Morris (Righteous Victims), who is unsparing of Israel's complicity in the Six Day War and, most importantly, in its aftermath. I'm interested in where you could possibly have been getting the details you're confidently providing in this thread.
Having a plan on the shelf for how to invade is different from actually intending to invade. Israel not only had a plan to preemptively attack Egypt - it was very actively training for this plan and then carried it out. In contrast, it's fairly clear now that Egypt did not plan to invade Israel in June 1967, and was not in any position to do so. Like you, I've also read Benny Morris' Righteous Victims (which only has a relatively short section on the lead-up to the 1967 war).
The two points I've been making here are:
1. The traditional narrative that Israel fought a defensive war in 1967 is highly questionable, at best. It does not seem that the Egyptians were planning to attack, the Israelis themselves had a major hand in the escalation leading up to the war, and the Israeli military was extremely confident that it would quickly defeat the Arabs (an assessment that the Americans shared) and wanted a war.
2. This narrative that Israel gained the West Bank and Gaza through a defensive war is then used to justify Israel's more than half-century military rule over the Palestinians. Even if the Israeli narrative were 100% correct, it would not justify imposing military rule over millions of people for decades, while slowly robbing those people of their land and subjecting them to regular violence and humiliation.
Righteous Victims has 2 whole chapters on the leadup to the Six Days War, which is like the centerpiece of the book. You can't be citing Righteous Victims, because it strenuously disagrees with virtually everything you've said here. What are you citing?
The only thing I wish to add is that this kind of “selectiveness” of facts by those who argue with Israel existence is by itself one of the main reasons for Israel creation in the first place.
