That is your opinion. But this purpose of this meeting is in black and white. Hamas doesn’t like that because its going to be cut off of funds. The US and Saudi Arabia being the largest donors to Palestine would want to implement some restrictions on cash flowing to Palestine that ends up in Hamas’ hands. This won’t be the case anymore. No cash period. All contribution will be in form of materials, goods...etc. Saudi Arabia rebuilt Gaza 6 times, twice in case of Lebanon. Hamas grew because of Arab/US funds that went to Hamas instead of going to the Palestinians. Hamas on the other hand, has built no hospitals, no schools, no housing. All done by Saudi Arabia. The Palestinian budget is paid by Arab countries. This conference is purely economic and has nothing to do with politics whatsoever. Saudi Arabia 3 last summits held in Makkah back in Ramadan along with all Islamic and Arab countries reaffirmed Palestinians right to establish their own country based on 67 border agreement with East Jerusalem as its capital. Hamas can now continue sucking the money of the Iranian people paid by Khamenei. There is only one internationally recognized legitimate government of Palestine and that is the Palestinian National Authority.We can make deductions about the political side from this. For example, lots of specific projects mentioned for Gaza and Lebanon etc but no mention at all of East Jerusalem. Also lots of investment in neighbouring countries (Egypt, Lebanon) for the specific purpose of absorbing Palestinian refugees, aka no right of return.
This isn't a conflict about money, it's about land and recognition of sovereignty and other symbolic rights.
