If the Blue is Israel, then it shows that the Israeli's also claim two thirds of Lebanon and part of Syria, as well as the Occupied Territories.
The blue area shows Israel to include the post-1948 borders plus the West Bank, Gaza Strip, and Golan Heights.
You claim that this map shows Israel asperations. It would seem to show the current boarders of Israel controlled territory. (Unless you are saying that Israel does not control this territory.
There is no asperation for Syrian land shown here. The Golan Heights were annexed in 1982 or 1983 after a referendum. The Druze, christians, Arabs, and Jews of the Golan heights are all Israeli citizens and most choose to serve in the army.
If you are such a fetishist for the 1923 borders that you do not accept Israeli annexation of this territory, you are relying on an agreement that set the Kingdom of Transjordan to be the palestinian state and the rest of the Mandate of Palestine from the Jordan River to the Medditeranian to be teh Jewish state. If you accept the 1923 borders as sacrosanct, then you cannot call the West Bank and Gaza strip occupied.
