Reza Behnam is an Iranian-American, partly  raised in America, not simply "an Iranian."
Unfortunately the major point of Behnam's letter, the continuous  expansion of Israeli settlements in to Palestinian land,  has not been addressed here.  As these settlements are blocking any possible two-state solution they have to be considered.
Just as Arabs have to acknowledge the right of Israelis to live peacefully within their own borders, so must Israelis respect  the same right for Palestinians.
That is the only road to Peace, all else is chimera.
