Why do Palestinian refugees have a separate refugee agency?

In short, the Palestinians do NOT possess a ‘right’ to return.

For too long, Palestinian groups have been nourished, indulged and sustained by their enablers to keep fighting for an annihilationist cause, rather than moving on, and creating prosperous lives for themselves.

Yes, it was a proposed solution to a conflict from the GA. If 181 had been accepted by both parties then it would be binding. However, as it was rejected by the Arabs it is not legally binding.

So what you're saying is Resolution 181 was purely advisory and not legally binding.

I haven’t stated Gazans do or don’t support Hamas. You have. Therefore, what evidence are you basing this on?

I'll see yours first.

Where is your evidence that the majority of Gazans don’t support Hamas?

The majority of Palestinians don't support Hamas. Please don't present your poll again which purports to speak for millions of people.

No they DO NOT have a ‘right’ to return.
The view that resolution 194 created a Palestinian right of return mischaracterises the resolution’s legal status. The UN General Assembly’s powers are limited, it cannot confer legal or binding rights. Therefore, the resolution is purely advisory it does not and cannot create a ‘right’ to anything including ‘return’.
Same goes for 3236.

Because their home is Palestine and they belong there. The countries with refugee camps don't want to take them.

The Palestinians DO have a right to return under Resolution 194, 1948.

Resolves that the refugees wishing to return to their homes and live at peace with their neighbours should be permitted to do so at the earliest practicable date, and that compensation should be paid for the property of those choosing not to return and for loss of or damage to property which, under principles of international law or in equity, should be made good by the Governments or authorities responsible.

Resolution 3236, passed on 22 November 1974, declared the right of return to be an "inalienable right".

Palestinians do NOT have a ‘right’ to return.

Throughout the world in the 1940s and 1950s (when the Palestinians became refugees) millions and millions of refugees were rehabilitated in the countries that had given them shelter.

600,000 Chineses fled to Hong Kong in 1949
It was tough, it was tragic, but they moved on.

14 million Hindu and Muslim refugees found shelter in India and Pakistan, respectively, following partition of the Indian subcontinent in 1947.
It was tough, it was tragic, but they moved on.

3.1 million fled North Korea to South Korea in the 1950-1953 conflict.
It was tough, it was tragic, but they moved on.

800,000 Jews had to flee Arab countries of Iraq, Egypt, Syria, Yemen, Algeria, Morocco and Tunisia.
It was tough, it was tragic but they moved on.

10 million ethnic Germans were brutally expelled from Eastern Europe when the borders were redrawn, not because they were Nazis, just because they belonged to the ethnic group that had lost the war. They had lived there for centuries.
These ethnic German refugees also wanted to return to their birthplaces. They did not want to return under foreign rule meaning they wanted Germany to recapture these territories forcefully.
All of Germany’s political leaders paid lip service to the refugee’s demands and public ally supported them but, in reality, did nothing to advance them. Germany focussed on the refugee’s full integration into Germany and pursued wealth redistribution to achieve this. By the early 1960s, the voices demanding a return had all but disappeared.
The German Government realised that to pursue the refugee’s desire to return to their birthplace would have resulted in further conflict and war.
It was tough, it was tragic, but they moved on.

700,000 Palestinians were expelled from the Mandate in 1948.
It was tough, it was tragic but it is time to MOVE ON.

What's your solution to the Palestinian refugees?

The status quo is obviously not feasible. The refugees should be allowed to return home and there isn't room due to stolen land. Palestine should initially be run by the UN in order to facilitate the rebuilding and then hold elections.

That's incorrect. UNRWA was established in 1949 to carry out humanitarian work for Palestinian refugees. A lack of a viable solution has meant a repeated renewal of the UNRWA mandate.

It was be good to have the two states envisaged in Resolution 181, 1947.

That's not related to UNWRA which was set up specifically to deal with the expelled Palestinians.
