The responsibility for resolving this issue should have been with the Europeans. For centuries these nations discriminated against and mistreated their Jewish residents. This mistreatment frequented led to extreme horrors that culminated during World War II. European nations should have reformed their policies and behaviors after the war and fully compensated their Jewish populations for this suffering and loss. Instead, the UN vote to create the state of Israel resulted in another extreme transgression, the displacement of Arab occupants and loss of their lands and homes. The current state of Palestinian-Israeli affairs continues to be a wholly unacceptable stalemate.
Suggestion:
Based on their original responsibility for this situation, I propose that Europeans nations provide most of the funds to build international airports in the West Bank and Gaza, a seaport in Gaza, and a railroad connection between the West Bank and Gaza. This could create a more sustainable economic and socially cohesive situation for the Palestinians and make a Palestinian state more realizable. I estimate that this would cost about $80 billion, which is a small amount considering all the economic and military costs spurred by this issue.
