That's 19th century logic.

As for "plainly preparing for", Israel launched the 1967 War. Two Prime Ministers of Israel admitted that:

“I do not think Nasser wanted war. The two divisions he sent to The Sinai would not have been sufficient to launch an offensive war. He knew it and we knew it.” — Yitzhak Rabin, fifth Prime Minister of Israel

“In June 1967, we again had a choice. The Egyptian Army concentrations in the Sinai approaches do not prove that Nasser was really about to attack us. We must be honest with ourselves. We decided to attack him.” — Menachem Begin, sixth Prime Minister of Israel

“Moshe Dayan, the celebrated commander who, as Defense Minister in 1967, gave the order to conquer the Golan…[said] many of the firefights with the Syrians were deliberately provoked by Israel, and the kibbutz residents who pressed the Government to take the Golan Heights did so less for security than for the farmland…[Dayan stated] ‘They didn’t even try to hide their greed for the land…We would send a tractor to plow some area where it wasn’t possible to do anything, in the demilitarized area, and knew in advance that the Syrians would start to shoot. If they didn’t shoot, we would tell the tractor to advance further, until in the end the Syrians would get annoyed and shoot. And then we would use artillery and later the air force also, and that’s how it was…The Syrians, on the fourth day of the war, were not a threat to us.’” — The New York Times, May 11, 1997
