Should Blair be a Middle East peace envoy

There appears to be hope on the horizon for peace in Gaza. I say hope, we had that before until Israel broke the agreement. There is an argument about the suitability of Tony Blair in this, but if he is involved in a just peace, so be it. 

It is a surrender by Hamas if they accept it, considering how the Palestinian Authority wanted to remove them by force in the past, when they had a democratic mandate, it will be an issue for them.  I am this will not stop the horrors in The West Bank. But it is a step to ending the ethnic cleansing in Gaza.
