Your point would be correct if for example there was a time when checkpoints didn't exist and the opposing sides views were welcomed but wait this did exist pre 48. You can say that the partition document drafted was unfair, but you have to acknowledge how it got there, notably my second point where the opposing side, Arabs and Palestinians boycotted partition plan from it's onset, i.e an option for a voice was refused by Palestinians And we know what happens next a 1.5 year war so how about your point, ease of movement etc... With hard guarantees that include a punitive measures valid in only means of true value land. Do you think Palestinians would agree and offer the guarantee with sureties? Otherwise why should israel take risk for no reward?
