Israel/Palestine

per wikipedia:

Settler colonialism occurs when colonizers invade and occupy territory to permanently replace the existing society with the society of the colonizers.[1][2][3]

Settler colonialism is a form of exogenous domination typically organized or supported by an imperial authority.[4] Settler colonialism contrasts with exploitation colonialism, which entails an economic policy of conquering territory to exploit its population as cheap or free labor and its natural resources as raw material. In this way, settler colonialism lasts indefinitely, except in the rare event of complete evacuation or settler decolonization.[5]

Settler colonialism was especially prominent in the Colonial empires of the European powers between the 16th and 20th centuries. The settling of Boers[6] in South Africa, British,[7] French, Portuguese[8] and Spanish[9] expansion in the Americas as well as the settlement of the Canary islands by Castile are classical examples of settler colonialism

Jewish settlements were not initiated by an "imperial authority". There has always been a Jewish presence in the area dating back centuries.

Jewish immigration has had the effect of displacing existing residents, so this characteristic of settler colonialism is shared.

I agree that use of the term "colonialism" in this context is a relic of the cold war and has degenerated into a generic slur that does not help Israeli-Palestinian relations.
