Hugh, I can agree with much of what you say, for I too have long supported a two state solution and grieve as the increasing settlements make that almost impossible.  However, Israel, as Palestine, contains a lot of people who want just ONE state-- their  own state-- from the river to the sea.  
While I don't believe most Israelis really   are "intent on  grinding the millions of Palestinians into the dirt" it seems too many are still blind to their existence and history, following the old slogan of "A land without  a people for a people without a land"                                .
But there is another side to this story-- all too many Arabs fail to see the right of Israel to exist ,and prefer their own version of a "single state from the river to the sea."
In short if we are to seek  Kerry's plan for a two state solution, we need to get over this one-sided bickering, and agree both sides have made mistakes but both deserve respect and a decent, secure society.
