This is ahistorical propaganda. Nakba was the ethnic cleansing of indigenous Palestinians in favor of invading Europeans. Israel was fully created through terrorism and war crimes, which continue at scale to this day.
No, that's false. "Nakba" refers to the exodus of the Palestinians during 1948. It says exactly that in the Wiki. The exodus came as a result of war, first between the local Arabs and the Jews, and more prominently when Arab armies joined the war against Israel after it was declared a state.
Israel was given statehood by a decision of the League of Nations, the body preceding the UN.
Verify that what exactly is false? It literally says that:
"The term is used to describe the events of the 1948 Palestine war in Mandatory Palestine as well as Israel's ongoing persecution and displacement of Palestinians"
> The Nakba (Arabic: النَّكْبَة, romanized: an-Nakba, lit. 'the catastrophe') is the Israeli ethnic cleansing[14] of Palestinian Arabs through their violent displacement and dispossession of land, property, and belongings, along with the destruction of their society and the suppression of their culture, identity, political rights, and national aspirations.
