Israel is simply developing on unused land, and improving infrastructure in the West Bank
Israel is developing on land unused by Palestinian settlements while providing infrastructure such as roads and in some cases police. Israel is a consolidate democracy, with strong civil liberties, and a strong a prosperous economy, Palestinians could be better off living side by side peacefully in this area with Israelis. Ending the development of and removing current settlements won’t end the conflict, as can be seen in Gaza.
The State of Israel was formed on 14th May 1948, after the Jewish populations successfully opposed British rule. All the bordering Arab countries followed this by invading the country and Israel fought and won territory throughout the former Palestinian region, in the First Arab-Israeli War. Israel won the territories of the West Bank, Gaza Strip, Sinai Peninsula and Golan Heights in the preemptive Six-Day War in 1967. Various conflicts continued from this until 1977 when talks between leaders of Israel and Egypt lead to the Camp David Accords and the Israel-Egypt Peace Treaty, with the Sinai Peninsula being returned to Egypt.
Jewish settlers are now simply using unclaimed regions that the Israeli forces have had to defend themselves against many antagonists on numerous occasions. Antagonists whose sole intention is to remove a jewish presences from the region altogether.
