Yes, but Palestine has no right of return, based that in U.N. General Assembly's 1948 Resolution 194 (III) calls for permitting refugees to return to their "homes" as legal support for an alleged "right of return" to the Jewish state. But General Assembly resolutions are nonbinding and do not take part of international law.
Also, it was rejected by Israel all by all
Arab states. After the settlement of a Jewish state and Palestinian state, Palestine can no longer claim that it is 'their state' and can return to it. Plus, the resolution would be permitted back only if they wanted to "live at peace with their neighbors,"
which is not
the case for Palestine. In the PLO's main goals, article 8 and 9, they show their plan to destroy Israel, which was only annulled in 1998. Article 8
: The phase in their history, through which the Palestinian people are now living, is that of national (watani) struggle for the liberation of Palestine. Thus the conflicts among the Palestinian national forces are secondary, and should be ended for the sake of the basic conflict that exists between the forces of Zionism and of imperialism on the one hand, and the Palestinian Arab people on the other. On this basis the Palestinian masses, regardless of whether they are residing in the national homeland or in diaspora (mahajir) constitute - both their organizations and the individuals - one national front working for the retrieval of Palestine and its liberation through armed struggle. Article 9
: Armed struggle is the only way to liberate Palestine. Thus it is the overall strategy, not merely a tactical phase. The Palestinian Arab people assert their absolute determination and firm resolution to continue their armed struggle and to work for an armed popular revolution for the liberation of their country and their return to it . They also assert their right to normal life in Palestine and to exercise their right to self-determination and sovereignty over it.
Israel cannot let the Palestinians into their country because there are 23
Arab states and 1
Jewish state, therefore if Israel let the Palestinian refugees in, it would become another Arab state, and would lose it's culture and be discriminated even more.
Adding, that in the Oslo Agreement in 1993, which was between PLO and Israel, PLO recognizes the State of Israel to exist in peace and security
So, since there is no right of return, a two-state solution is the only
way to go. Israel will not
allow Palestine to enter into any more chaos, even if they believe it is Israel itself. The Israeli delegates resolution and question of are about fixing the situation and creating a future where the two states can live peacefully
along side eachother and see the years of conflict as a dark patch in the Israel and Palestinian relationship.
