Then you're either incredibly naive, or you're transparently hoping for the destruction of Israel from within.
Which is it?
Feel free to explain why you think it's a marvelous idea for Israel to welcome into its land a flood of millions of people who wish to destroy Israel and Jews. That's not to say that all Palestinians do, but there are clearly huge numbers of them who fervently wish it, enough so that a "right of return" would overwhelm Israel like christening a highway for trojan horses.
This is either what you want to happen, or you're so amazingly ignorant of the situation that it's hard to take your pronouncements about "what Israel should do" seriously.
Now, let's take it to the next level.
Why should Europe welcome into its land a flood of millions of people who wish to destroy Europe and Europeans?
Yet, Europe (and America) are expected to welcome millions of hordes of Third Worlders. If they don't, Abe Foxman will express concern about their racism. Why the double standard?
