In Gaza and Ukraine right now, the colonial powers simply want the territory, and are largely indifferent or are openly hostile to the continued physical existence of the people who live there.
For example it is not untrue to say that Yemen successfully fought the UK to gain independence (at least South Yemen). In Rhodesia (now Zambia and Zimbabwe) and Nyasaland (Malawi) calls for independence (by ANC, NAC, etc.) was met with crackdown by the white Rhodesian army (who ruled south Rhodesia post independence with apartheid). In Kenya the Mau Mau rebellion was brutally suppressed by the British Army, with over 35000 insurgents killed by British colonial forces. The Mau Mau lost, and Kenya peacefully gained independence a few years later.
Even though most former British colonies got their independence by voting in a pro-independence government who negotiated for independence between the mid 1960s and the 1980s, which the British peacefully accepted (with rare exceptions), the years prior, any independence prospects were definitely met with various tactics to prevent their success, including violent and armed colonial warfare.
