Nations become Nations because people fight, die and, eventually, succeed in taking the land upon which those nations are built.
This is how the United States, Ireland, Russia, China, Britain, France, Sweden, Thailand, Iraq, Syria, Egypt, Saudi Arabia, Jordan, Turkey, Yemen, Oman and every other Nation on the planet were formed.
This is how Israel was formed as well. This is why Palestine is not, has never been and will not be a Nation.
Palestine has never been a Nation. The existence of a group of people who choose to call themselves a name created by Romans nearly 2,000 years ago neither necessitates nor creates a Nation. The existence of a people who chose to flee (as they do in Syria) and become refugees rather than fight for their homeland does not create nor does it necessitate a Nation. A group of people who choose to call themselves Palestinians and who use terrorism to bully the world into coming to their aid and who constantly poke a bear in it’s lair so that said bear will come out and mail them neither creates, justifies nor necessitates a Nation.
Palestine has been a lie since 1967. Before 1967, Palestine was naught but the name of a province of Rome and half of the name of a British Mandate.
The people who chose to brand themselves Palestinians chose to flee rather than to stand and fight.
