WHY ISRAEL representation allowed in MUN events of PAKISTAN ?

So called awful sort of rivalry for the state Pakistan towards the  ISRAELI prospectives and its existence in world .

It was Pakistan’s founder words on Israel creation  that he would not  have ISRAEL  on the map of te world if no involvement of USA and UK in the creation process .But regardless whatever happened world knows it drastically .

Pakistan never accepted Israel as a country and eliminated it for passport consideration . But in the MODEL UNITED NATION events which are usual in many popular universities around, the country(Israel) which never been considered the one is allowed to enroll delegation and compete in the resolution scenarios.

Either founder made a mistake  with his comment or its his  people who never showed  thankfulness for his efforts .
