The Peace with Egypt was enforced by Egypt's security forces and is being continued by Egypt's security forces, i.e., the Egyptian Army. The peace with Jordan is being guaranteed by the Jordanian security forces. The question Israel has to answer is can a peace be enforced by Palestinian security forces. In Egypt, and Jordan, they are well equipped and trained. Israel seems to keep insisting that Palestinian forces not be equipped or trained to the same level. This appears short sighted at the very least.
