As long as the religious hold political power in the US, israel will never face a real threat of embargo. American right wings think the nation is a sign of rapture, as well as a convenient place to send the jewish diaspora when “the time comes,” and so actively do whatever they can to protect it.

And since they hold enough power to disrupt any economic reppercussions, israel can do whatever it likes

The 1949–1956 Palestinian expulsions were a continuation of the 1948 expulsion and flight of Palestinian Arabs from Israeli-controlled territory that occurred after the signing of the ceasefire agreements.[1][2][3][4] This period of the exodus[5] was characterised predominantly by forced expulsion during the consolidation of the state of Israel and ever increasing tension along the ceasefire lines ultimately leading to the 1956 Suez Crisis.[6]

Between 1949 and 1950, according to historian Benny Morris, Israel had displaced and expelled between 30,000 and 40,000 Palestinians and Bedouin.[7] Many villages along the ceasefire lines and the Lebanon border area were also leveled, many emptied villages were resettled by new Jewish immigrants and demobilized Israeli military forces.[8][9]

The 1967 Palestinian exodus or Naksa[1] refers to the flight of around 280,000 to 325,000 Palestinians[2] out of the territories captured by Israel during and in the aftermath of the Six-Day War, including the razing of the Palestinian villages of Imwas, Yalo, and Bayt Nuba, Surit, Beit Awwa, Beit Mirsem, Shuyukh, Al-Jiftlik, Agarith and Huseirat and the “emptying” of the refugee camps of Aqabat Jaber and ʿEin as-Sultan.[3]

It’s definitely why a significant chunk of the US supports them, notably a lot of the Bush administration support had that kind of haze hanging over it. Israel’s government knows this, too, but they (probably rightly) figure that long term this is pointless masturbation and their goals align for now so they’ve been playing nice with the end-times worshippers.

Israeli support is paramount among the religious right wing movement in the US, specifically for this reason.
