Envoy Tony Blair says the quartet, frustrated with the peace process, will seek border and security proposals first from Israelis and Palestinians...

Question: You are taking a more active role in the peace process? Is that because the U.S. is stepping back?

[Tony Blair's answer] The U.S. is still very much there, but it's also saying to the international community, "You've got to step up with us here." If this situation deteriorates, you are going to have a major problem in the region. However difficult or frustrating it gets for me — and this is my 72nd visit here in four years — I do it because I think it's of profound importance to the region and to our security.

So you are not going away?

Correct.
