While Hamas and other Palestinian armed movements may have been used as Israel’s rationale for its hardline stance, it was not a primary factor in the failure of the Oslo Peace Process. The roots of that failure lie in multiple variables: Israel’s strategic decisions, its ongoing occupation, unconditional U.S. support for Israel, and the broader dynamics of Palestinian resistance. Suppose Hamas were truly the core issue in the failure of Oslo. Why would Israel continue to expand settlements, target civilians, and tighten its control over the West Bank—a region where, unlike in Gaza, the Palestinian Authority promotes non-violence and actively suppresses those who resist occupation by force?
