Zionism is a settler colonialism project that was able to really start with the support of British Imperialism. Zionism as a political movement started with Theodore Herzl in the 1880s as a 'modern' way to 'solve' the 'Jewish Question' of Europe.

Since at least the 1860's, Europe was increasingly antisemitic and hostile to Jewish people. Zionism was explicitly a Setter Colonialist movement and the native Palestinians were not considered People but Savages by the Europeans. While Zionist Colonization began before it, the Balfor Declaration is when Britain gave it's backing of the movement in order to 'solve' the 'Jewish Question' while also creating a Colony in the newly conquered Middle East after WWI in order to exhibit military force in the region and extract natural resources.

That's when Zionist immigration started to pick up, out of necessity for most as Europe became more hostile and antisemitic. That continued into and during WWII, European countries and even the US refused to expand immigration quotas for Jewish people seeking asylum. The idea that the creation of Israel is a reparation for Jewish people is an after-the-fact justification. While most Jewish immigrants had no choice and just wanted a place to live in peace, it was the Zionist Leadership that developed and implemented the forced transfer, ethnic cleansing, of the native population, Palestinians. Without any Occupation, Apartheid, and ethnic cleansing, there would not be any Palestinian resistance to it.

Herzl himself explicitly considered Zionism a Settler Colonialist project, Setter Colonialism is always violent. The difficulty in creating a democratic Jewish state in an area inhabited by people who are not Jewish, is that enough Palestinian people need to be 'Transferred' to have a demographic majority that is Jewish. Ben-Gurion explicitly rejected Secular Bi-national state solutions in favor of partition.

Zionism’s aims in Palestine, its deeply-held conviction that the Land of Israel belonged exclusively to the Jewish people as a whole, and the idea of Palestine’s “civilizational barrenness" or “emptiness” against the background of European imperialist ideologies all converged in the logical conclusion that the native population should make way for thenewcomers.

The idea that the Palestinian Arabs must find a place for themselves elsewhere was articulated early on. Indeed, the founder of the movement, Theodor Herzl, provided an early reference to transfer even before he formally outlined his theory of Zionist rebirth in his Judenstat.

An 1895 entry in his diary provides in embryonic form many of the elements that were to be demonstrated repeatedly in the Zionist quest for solutions to the “Arab problem ”-the idea of dealing with state governments over the heads of the indigenous population, Jewish acquisition of property that would be inalienable, “Hebrew Land" and “Hebrew Labor,” and the removal of the native population.

Israel justifies the settlements and military bases in the West Bank in the name of Security. However, the reality of the settlements on-the-ground has been the cause of violent resistance and a significant obstacle to peace, as it has been for decades.

This type of settlement, where the native population gets 'Transferred' to make room for the settlers, is a long standing practice.

The mass ethnic cleansing campaign of 1948:

• Plan Dalet
• Declassified Massacres of 1948
• Details of Plan C (May 1946) and Plan D (March 1948) .

Further, declassified Israeli documents show that the Occupation of the West Bank and Gaza Strip were deliberately planned before being executed in 1967:

• Haaretz, Forward

While the peace process was exploited to continue de-facto annexation of the West Bank via Settlements

• (Oslo Accord Sources: MEE, NYT, Haaretz, AJ).

The settlements are maintained through a violent apartheid that routinely employs violence towards Palestinians and denies human rights like water access, civil rights, etc. This kind of control gives rise to violent resistance to the Apartheid occupation, jeopardizing the safety of Israeli civilians.

The apartheid regime is based on organized, systemic violence against Palestinians, which is carried out by numerous agents: the government, the military, the Civil Administration, the Supreme Court, the Israel Police, the Israel Security Agency, the Israel Prison Service, the Israel Nature and Parks Authority, and others. Settlers are another item on this list, and the state incorporates their violence into its own official acts of violence. Settler violence sometimes precedes instances of official violence by Israeli authorities, and at other times is incorporated into them. Like state violence, settler violence is organized, institutionalized, well-equipped and implemented in order to achieve a defined strategic goal.
