And the air attack followed the massing of troops by the arab nations on the Israeli border area and the closing of the Straits of Tiran to Israeli shipping which Israel had declared previously that it would consider an act of war.

The Straits of Tiran was regarded by the Western Powers and Israel as an international waterway[28][51][52] but its legal status was the subject of international controversy.[53] The Arabs believed that they had the right to regulate passage of ships while Israel, with the support of other major world powers, countered that the Arab claims were legally not supportable.[54] In 1967 Israel reiterated declarations made in 1957 that any closure of the Straits would be considered an act of war, or a justification for war.[55][56] On May 22 Nasser declared the Straits closed to Israeli shipping.[28][57] Nasser stated he was open to referring the closure to the International Court of Justice to determine its legality, but this option was rejected by Israel.[58][59] Egyptian propaganda attacked Israel,[60] and on May 27, Nasser stated "Our basic objective will be the destruction of Israel. The Arab people want to fight."[61]
