the entire process was founded on the premise of two countries existing side-by-side... since right now we have a country (israel) existing side-by-side with a non-country (west bank and gaza). the ethnic makeup of those countries is not really relevant. if palestine got a massive influx of afghans or persians, it'd still be palestine (not "the arab state"). if israel (continues to) gets massive amounts of arabs, it's still going to be a country (just not "the jewish state"). this is really about semantics, which is a non-sequitor, which suggests to me that perhaps you are projecting... and it is you who does not want two states, under any circumstance.
