" Genuine " according to you ?
To me the exact opposite of your statement is nearer the truth, as was shown to some degree in the quote of yours that you decided to repost. It went some way into showing some of the
actions taken by Palestinian leaderships and they underscore the point I was making.
When Hamas won the elections in 2006 ( Palestinian self determination albeit a limited one ) the result was met with an almost blanket freeze out of the PAs patrons accompanied by the suspension of funds by the US/EU , the UN and the withholding of tax payments owed to the PA by Israel. The self proclaimed champions of democracy sometimes show their true feelings/contempt for it as they did here , though not an isolated occasion for those who study it .
Behind the scenes the US , Israel and Abbas and co were plotting a coup to ouster Hamas. Hamas , however , preempted it and threw out Fatah from the Gaza strip. So much for any alleged " inaction " from the Palestinian leaderships. This was ,btw , included in the original post of yours you quoted , mentioned above.
For sure there is much wrong with Palestinian factional infighting ,corruption and other stuff and they do shoulder a certain amount of responsibility for the lack of unity but to ignore the massive influence of the other players in this conflict is to miss the elephant sat next to you imho
The Palestinian political factions have been forced by their patrons and occupiers into a hopeless and destructive cycle of violence/harrassment against each other that is just a modern day example of the old imperialist tactics of divide and conquer that has played out , with great success , throughout history.
It is the outside influence that is brought to bear on the Palestinians that is the " predominant " reason for the abject failure for Palestinian unity and not any inaction of their leaderships
