Why were the Oslo Accords never implemented Who was at fault ?

Israel was at fault especially if we look at the major Impacts of the Oslo Accords on the Ground:
  • Most Palestinians experienced a deepening of Israel's control over their lives and land, with the PA acting as a subcontractor for Israel’s occupying army. The PA’s paramilitary police, which are armed and trained by the U.S., continue to work closely with the Israeli army to suppress political dissent and resistance to Israel’s occupation and apartheid system, with the PA leadership becoming increasingly authoritarian over time.
  • Under the terms of the Oslo Accords, the West Bank was divided into three separate areas: Area A, comprising 17% of the West Bank where most Palestinians live, is supposed to be under PA civilian and security control (under the overall control of the Israeli army); Area B, comprising 23% of the West Bank, is under PA civilian control and full Israeli military control; and Area C, comprising 60% of the West Bank where most settlements are located, is under full Israeli military and civilian control.
  • Between 1992 and 2000, Israel nearly doubled the number of Jewish settlers living illegally on occupied Palestinian land in the West Bank,from 100,500 to 190,206. During the same period, the number of settlers living in occupied East Jerusalem, the putative capital of a Palestinian state, increased from 141,000 to 167,230. As of 2023, there are upwards of 500,000 Israeli settlers in the West Bank and 200,000 in East Jerusalem, in more than 200 official and unofficial settlements.
  • Israel began increasing restrictions on Palestinian movement within the occupied territories and between the occupied territories and the outside world, including a new permit system. At any given time, there are more than 500 physical barriers to Palestinian movement in the West Bank and East Jerusalem, including military checkpoints where Israeli soldiers routinely humiliate and harass Palestinians trying to cross. These restrictions - which Israeli settlers living illegally in the same territory are not subject to - cause great hardships for Palestinians, preventing the sick from accessing medical care, students from going to school, farmers from reaching their land, obstructing commerce and business, and separating families and friends.
  • Israel built a ring of settlements and a wall around the expanded boundaries of occupied East Jerusalem, severing it from the West Bank, cementing Israeli control over the city and preventing most Palestinians on the outside from entering to worship, visit family and friends, do business, or study. Once a center of religious, cultural and economic life for Palestinians in the West Bank, now most aren’t allowed to enter Jerusalem.
  • Israel separated Gaza from the West Bank and East Jerusalem, even though Oslo’s Declaration of Principles states “the two sides view the West Bank and Gaza as a single territorial unit,” and built an electrified fence around Gaza to keep people in. Since 2007, Israel has imposed a crippling siege and naval blockade on Palestinians in Gaza, which has been condemned as illegal by the UN and human rights organizations.
  • The downtown core of Hebron, the largest Palestinian city in the West Bank, was divided into two sections, one controlled by the PA (H1), and the other, where a few hundred radical Jewish settlers have implanted themselves, by the Israeli army (H2). As a result, the once bustling downtown core has become a ghost town, with Palestinian storefronts welded shut by the Israeli army. The main thoroughfare, Shuhada Street, has been dubbed “apartheid street” because Palestinians are forbidden from walking on it while Israeli settlers can use it freely.
