The outbreak of the Six-Day War was Israeli-initiated. It could well have been to stop an invasion by Nasser and the other Arab forces, but some Israeli officials have said otherwise.
I believe the military events of the Suez Crisis were also initiated by Israel, although I read (in a historical novel :lol

that Nasser's seizing of the Suez Canal violated international law and hurt Israeli trade (also British and French trade).
Not true. The Six Day War was Arab initiated. While Egypts blockade of the Straights of Tiran was Casus Belli itself, there were many more hostile actions that put Israel in an untenable position forcing Israel to take action.
Here is a previous post I made. There might be some comments that are not directed to you
The blockade of The Straits of Tiran was recognized Casus Belli and was itself all the justification Israel needed to strike. Even LBJ said
“If a single act of folly was more responsible for this explosion than any other it was the arbitrary and dangerous announced decision that the Straits of Tiran would be closed. The right of innocent, maritime passage must be preserved for all nations”. - US President Lyndon Johnson - June 19th 1967
The fact is even though Israel was well justified in striking because of the Straits of Tiran blockade on May 22nd, they did not do so and did try and let diplomacy work. The Straits of Tiran blockade was one of only many proximate causes that forced Israel to take pre-emptive defensive military action on June 6, 1967. The Arab actions prior to the blockade such as terrorist activity emanating from the various Arab countries, threats, Syrian shelling from the Golan and the attempt to cut off one of Israels main water sources, as well as combined with Arab actions during and after the Tiran blockade such the massing of Arab armies on Israels border, Egypt kicking out UN Peacekeepers in the Sinai, Egypt moving troops in and massing troops in the Sinai after kicking the UN out even thought it was supposed to be a DMZ, continued shelling/terror activity, the Egypt, Syria Jordan military pact and the constant threatening rhetoric calling for the destruction of Israel, all give Israel more than enough justification to strike even without the Straits of Tiran blockade. Even when the war began Israel urged Jordan to stay out and only struck Jordan after Jordan attacked.
Despite having many times more than enough justification to take action Isreal did try to give diplomacy a chance. But Israel was in an untenable position. They were a country of 3 million surounded on all sides by an enemy numbering 110 million with over 3 times the combat aircraft, tanks and other arms than Israel. The Arab Armies were many times the size of Israels 50,000 with 214,000 reserves. While Israeli troops were better trained they were mostly reserves so their mobilization was crippling their already shaky economy and they could not maintain such a mobilization for any length of time without imploding their economy. The fact is the longer they waited the weaker they became making for more and more resultant casulaties and damage they would suffer from. Even more importantly the longer they waited the less the chance for victory would be and losing means Israels complete destruction.
All the above while Nasser and other Arab leaders are making speaches and spouting off about anihilating Israel in a holy war and driving the Jews to the sea. Only a fool would not take these mortal threats seriously and not act as quick as possible.
Memorandum From the Central Intelligence Agency's Board of National Estimates to Director of Central Intelligence
Washington, May 26, 1967.
/1/Source: Johnson Library, National Security File, Country File, Middle East Crisis, Vol. II. Secret
The Israelis face dismaying choices. Surprised and shaken by Nasser's action, they failed to take the instant military counteraction which might have been most effective. If they attack now they will face far more formidable opposition than in the rapid campaign of 1956. We believe that they would still be able to drive the Egyptians away from the entrance to the Strait of Tiran, but it would certainly cost them heavy losses of men and materiel. We are not sure that they have sufficient stockpiles of ammunition and equipment for a war lasting more than three or four weeks, and it is possible that they would not embark upon a major campaign without prior assurances from the US of adequate resupply.
But the alternative for the Israelis is perilous. To acquiesce in the permanent closing of the Strait of Tiran would constitute an economic and political setback from which no early recovery would be foreseeable. The Israelis would expect, correctly we believe, that the Arabs over the long run would be encouraged to undertake new and still more dangerous harassments. We are inclined to believe that unless the US and other major powers take whatever steps are necessary to reopen the Strait, the Israelis will feel compelled to go to war.

…(the crisis had developed because) “Eshkol threatened to march on Damascus, occupy Syria and overthrow the Syrian regime. It was our duty to come to the aid of our Arab brother. It was our duty to ask for the withdrawal of UNEF.

We have reached the stage of serious action and not of more declarations." - Gamal Abdel Nasser speech
Nasser challenged Israel to fight almost daily. "Our basic objective will be the destruction of Israel. The Arab people want to fight," he said on May 27 The following day, he added: "We will not accept any...coexistence with Israel...Today the issue is not the establishment of peace between the Arab states and Israel....The war with Israel is in effect since 1948."
King Hussein of Jordan signed a defense pact with Egypt on May 30. Nasser then announced:
"The armies of Egypt, Jordan, Syria and Lebanon are poised on the borders of Israel...to face the challenge, while standing behind us are the armies of Iraq, Algeria, Kuwait, Sudan and the whole Arab nation. This act will astound the world. Today they will know that the Arabs are arranged for battle, the critical hour has arrived. We have reached the stage of serious action and not declarations."

"The characteristic of this situation is the declared aim of one side not to win concessions from the other. Their demand is that Israel should cease to exist - indeed has never existed. ...What had to be sought was not merely how to avoid war but to create the conditions of peace. One condition of a lasting peace must be the recognition that Israel has a right to live. Israel had been for nearly 20 years a member of the United Nations entitled to the respect and protection of the United Nations."- Prime Minister Harold Wilson The Times
