Why are Pakistanis so emotionally invested in the Israel/Palestine conflict?
I perfectly understand Palestinian frustration. However, there's also a question of what to do today, how can Palestinians get the best deal for themselves now. Lamenting historical losses won't help at the moment--one must look forward. I think you'll agree that war probably won't get them what they want.
Personally, I think the best course would be for Gaza to try an become a mini-Singapore. Palestinians seem to be fairly well-educated, so it shouldn't be difficult, once the capital that flows into Gaza is used for business instead of weapons. That will improve the lives of Palestinians, get the attention of outside investors (and their politician allies), and perhaps even entice Israel to sign a deal with them. Then everyone can concentrate on solving the problem in the West Bank.
Gaza is easy compared to the West Bank, since Israel has no settlements there, and has exhibited no territorial ambitions there. It has a border with Egypt and access to the Mediterranean.
Every other idea has been tried, why not try mine?
