Nevertheless, if we will just presume that everything the Israeli government says is false, we're in a dead-end here... It is not ethical for the spokesperson of an Army to provide false information.

Lol.

I'm sorry to tell you, the Israeli government lies a lot, even to the whole world. Here is an example that is easily proven to be false and was very clearly a massive lie regarding the 6 day war.

Initially, both Egypt and Israel announced that they had been attacked by the other country. Gideon Rafael, the Israeli Ambassador to the UN, received a message from the Israeli foreign office: "inform immediately the President of the Sec. Co. that Israel is now engaged in repelling Egyptian land and air forces." At 3:10 am, Rafael woke ambassador Hans Tabor, the Danish President of the Security Council for June, with the news that Egyptian forces had "moved against Israel".[1] and that Israel was responding to a "cowardly and treacherous" attack from Egypt..."[2] At the Security Council meeting of June 5, both Israel and Egypt claimed to be repelling an invasion by the other,[1] and "Israeli officials – Eban and Evron – swore that Egypt had fired first".[3] On June 5 Egypt, supported by the USSR, charged Israel with aggression. >>Israel claimed that Egypt had struck first, telling the council that "in the early hours of this morning Egyptian armoured columns moved in an offensive thrust against Israel's borders. At the same time Egyptian planes took off from airfields in Sinai and struck out towards Israel. Egyptian artillery in the Gaza strip shelled the Israel villages of Kissufim, Nahal-Oz and Ein Hashelosha..." In fact, this was not the case,[4] The US Office of Current Intelligence "...soon concluded that the Israelis – contrary to their claims – had fired first"[5] and it is now known the war started by a surprise Israeli attack against Egypt's air forces that left its ground troops vulnerable to further Israeli air strikes. Though Israel had struck first, Israel initially claimed that it was attacked first.** Later it claimed that its attack was a preemptive strike in the face of a planned invasion.[6]
