You are either missing or completly ignoring a very obvious fact. The reason those other Arab states have refused to grant Palestinians citizenship is that doing so would validate Israel's denial of these people's right of return. Giving them citizenship in another country would bolster Israel's false argument that they have no right of return since they are now citizens of another state. The solution is quite simple. END THE OCCUPATION AND GIVE THE PALESTINIANS THEIR BASIC HUMAN RIGHTS WHICH YOU HAVE BEEN DENYING THEM FOR DECADES!!! How many people do you think you can go on fooling forever??
