I think a lot of people just think they will steal Palestine and then be satisfied, forgetting that greed, arrogance, and lebensraum know no bounds. Why would Israel want tons of fighter jets? It's not to wipe out a million starving Palestinians in Gaza, you don't need jets for that. And this should come as no surprise, since David Ben-Gurion said that the success of the 1948 U.N. partition plan of Palestine was part of a larger plan:

Zionist leaders, in particular David Ben-Gurion, viewed the acceptance of the plan as a tactical step and a stepping stone to future territorial expansion over all of Palestine.

and the early terrorist groups that established Israel and the IDF also expressly stated expansion was their aim:

Irgun emblem. The map shows both Mandatory Palestine and the Emirate of Transjordan, which the Irgun claimed in its entirety for a future Jewish state. The acronym "Etzel" is written above the map, and "raq kach" ("only thus") is written below.

Fun fact about the 1948 U.N. partition plan:

The Arab Higher Committee, the Arab League and other Arab leaders and governments rejected it on the basis that in addition to the Arabs forming a two-thirds majority, they owned a majority of the lands.[20][21] They also indicated an unwillingness to accept any form of territorial division,[22] arguing that it violated the principles of national self-determination in the UN Charter which granted people the right to decide their own destiny.

And Israel bribed, threatened, and offered loans (given by the U.S.) to countries to vote in favor of the partition plan, so anyone who supports Israel on the basis of justice or fairness really doesn't have a leg to stand on.

In that link, the section Reports of pressure against the Plan shows just how anti-semitic Zionism is.
