The IRA sat down with the people they had to negotiate with, though, because the UK were a party to the conflict, so there is no comparison with that situation. To explain further, what is being proposed here is that a third party is involved and it won't work because the negotiation has to be between the parties to the conflict, together with helpers of their choosing. Does that explain it better?
The alternative is not more fighting, no. The alternative is very clearly that we have a bit of respect for Palestinians and allow them to decide who they want at the negotiating table, and proceed with good faith. It should be Arab partners liaising with the PLA and Palestinian reps to decide who this should be.
There is no hope in hell that Netanyahu will agree to a real, fair and reasonable, equal two state solution without significant international pressure, we know this because he has set out his stall. That is the key thing we should be trying to find solutions for. There is no possibility that Blair will be able to exert pressure on Israel, it is more likely that he will try to convince the Arab world to agree to a very limited and controlled situation in favour of Israel and this will cause more conflict and then Blair et al will say "we tried".
So for a real 2 state solution, the only thing which would bring lasting peace, it has to be a real negotiation between the parties to the conflict, with international pressure brought to bear to ensure that it is a fair and reasonable and equal solution. The Arab world have agreed to a 2 state solution and they will already know what they think is a good starting point for a fair and equal solution, so let them liaise with Palestinians and set out their stall, and let that be the starting point. They do not need Blair. International leaders will be needed to facilitate.
Blair could however represent Israel is that is what Israel wants.
