I love Islam, All my ancestors are muslims. But the posture the arab world has taken with Israel in the past is unworkable and has led to a conflict raging for 70 years. The arab world must realize, Islamic world is in a situation where they are totally inferior to christendom-jewish world. You can act like it doesn't exist and continue on the pointless war path, but your just dragging it out.
When your on the weaker side of the table which arabs seem to lack any history of this due to the long 1000 year golden age from the 9th till 18th century, u must negiotate from a stand point on 'how much can I get' not from the point 'I want Israel gone and wiped out' as that is what a strong people can say.
For example if Someone robbed my house, I can fight all day and lose so much in the process and never get the house back, in-fact I may even lose getting 'part' of it back. So what u do in that situation is get as much concessions as u can for Palestine and accept the loss part. It's better getting a part of ur house back then nothing right? Then keep ya head down and build up your strength over time(stealh wise).
