The PA has violated the oslo accord so many times that it should have been declared null and void, Rabin didn't sign the agreement so over a thousand Jew civilians would be killed and many more thousands injured.

Tourist visa are good for three month and that has not changed. What has changed is extending the tourist visa beyond three month. and that is not a violation of the Oslo accord.
