Israel

Sadly I think you are right. He's been heavily involved since at least the mid 80s when he was Foreign Minister and spokesman.

I wonder if the loss of his brother has affected him to the extent he's incapable of accepting peace.

You don’t seem to be contradicting my view my view that there will never be peace while Netanyahu is involved.  

There are plenty of Israelis who support the two state solution. 

Israel is isolating itself more and more at the moment.  If the west were to stop arming them, they may have to come to the negotiating table. 

Pie-in-the-sky idea, but what the West Bank and Gaza needs is free and fair elections for the first time since 2006 - and whilst they weren't free and fair then either, it's long overdue that actual Palestinians were asked who they want to lead them...

I read somewhere that Israel agreed to 93% of the Palestinian demands for a two state solution and still the Palestinians would not agree to terms. It may have been during the Oslo accords.

Gazan democracy. One man, one vote. Once.

Sounds fair enough to me, Stuart, but isn`t this ( roughly ) what the UN envisaged in 1947?
The Jews were happy with this at the time; the Arabs somewhat less so.
I can`t see either side agreeing to this now.  I especially can`t see the Israelis ever agreeing to go back to pre 1967 borders, let alone 1948.

The world was very different in 1948.   
"In their wisdom", the West decided that 20 centuries of prejudice, persecution and pogroms,  ( culminating in the Nazis` recent attempt to exterminate the entire race ) were enough, and that the Jews should finally have somewhere where they could live in safety.
Rightly or wrongly, that was the thinking behind it all.
At the time, there was already a large Jewish presence in Palestine, and the UN attempted to draw up borders, reflecting those different population centres.
Also, at the back of it`s mind, the West might well have considered the fact that the Jews would be returning to a land, from which they themselves had once been expelled.  Who knows?
With the benefit of 75 years of hindsight, maybe the UN would have acted differently.
On the other hand, with the benefit of those same 75 years of hindsight, maybe the Arabs would have left well alone, and settled for a far smaller state of Israel, then the one we have now.

A two state solution is indeed something to be hoped for.  But right now, it sadly doesn`t look a realistic prospect.
It`d be like locking Tommy Robinson and Anjem Choudhary in a caravan together.

You were correct.

Iraqi militia groups rather than Iraq itself?
