The right wing settlers movement in Israel is feeling emboldened by the first appointments made by Trump. They think that they have already been given license to annex the West Bank, to confiscate more Palestinian land, to build more settlements, to demolish more Palestinian homes, to remove Palestinian communities, to force Palestinians to leave, and more.
These people and their actions are strategic threats to the State of Israel. Annexation of even parts of the West Bank will lead to (at the minimum) the freezing of peace treaties with Egypt, Jordan, the UAE, Bahrain, and Morocco.
If this happens, forget about normalization with Saudi Arabia. The same threats to Israel exist if there is an attempt to build Israeli settlements in Gaza or in Lebanon. Don’t think that Trump will save Israel if Israel tries to commit political suicide.
