Israel killing civilians in Gaza and the West Bank There is a lesson in that period in that the violence was in some sense less about Israeli actions, which were moving towards peace and statehood, than about intra-Palestinian struggles over peace and spoiling attempts. — Count Timothy von Icarus
It's this crux that is mistaken, the Oslo Accords was the exact opposite of what you were saying. It was the completion of Israel's control of the Occupied Territories, not intent to give Palestinians their own sovereignty. That changes your whole picture of the motives for the attacks.
"Oslo was not designed to lead to Palestinian statehood or self-determination, in spite of what the P.L.O.’s leaders at the time appear to have believed. Rather, it was intended by Israel to streamline its occupation, with the Palestinian Authority acting as a subcontractor. In Oslo and subsequent accords, the Israelis were careful to exclude provisions that might lead to a Palestinian political entity with actual sovereignty. Palestinian statehood and self-determination are never mentioned in the text, nor were the Palestinians allowed jurisdiction over the entirety of the occupied territories. Israel’s intention is even more clearly visible in the expansion of illegal Jewish settlements in the occupied territories, which followed the start of the Oslo process. There were fewer than two hundred thousand Israeli colonists in the occupied West Bank and East Jerusalem when negotiations began. Now, according to the Times, there are about six hundred and fifty thousand of them.
The P.L.O. leadership, for its part, played a weak hand poorly. It failed to capitalize on the expertise that its delegation had accrued in Madrid and Washington in the two years prior, sending to Oslo inexperienced negotiators with little knowledge of the situation in the occupied territories or international law. As a result, Oslo reinforced rather than evened out the political imbalance between Israel, an undeclared nuclear power supported by the world’s sole superpower, and the Palestinians, a stateless people living under occupation or in exile. With the weight of the United States tipping the scales heavily in its favor—diplomatically, militarily, and through pressure on the Arab states—Israel was able to impose its will, entrenching an apartheid system in which millions of Palestinians live under military rule, with no rights or security, while Israel appropriates their land, water, and other resources. The only part of Oslo that was faithfully implemented, in fact, is the protection that the P.A. provides to Israel by policing its own people."
