Pretty much the same, with the addition that I do not believe one can separate either the leaders of those nations represented, or their nations, from the faiths with are associated with them.
Any movement toward peace must acknowledge the religious aspect of the divisions. That does not mean that we must pray with heretics, Muslims, or Jews. We do not have to offer an Amen along with theirs, nor must we bow our heads as they pray, but we have to realize that some of the people participating in these conflicts hold onto their faith as the one beautiful and unifying thing in a life that closely resembles Hell on Earth. They believe sincerely and deeply, and though they are sincerely wrong, God Almighty can and does use the good will of that sincerity to draw them closer to Himself and Holy Orthodoxy.
If we are to call them to true peace which lies in Jesus Christ alone-through our presence and actions- if we are to call them to talk with one another and lay down their swords, we must realize that they are a people of faith and prayer who will express that faith as they search for peace, and they will do it in our presence as we call enemies to meet together.
That being said, I think events like the one at Assisi where pagan idols sat atop Roman Altars rightfully put everyone on edge. It is a difficult road to walk, and I pray the Ecumenical Patriarch is given the grace to travel it according to the will of God and not man. He sat apart from the other professed Christian faiths, the Muslims, Jews, and the political delegations which sat abreast the Pope. Perhaps that was one of his conditions to help alleviate any scandal which the meeting might cause.

Yes, well, if we were there praying our prayers with them in the neighborhood, I'd see that as the same as what the Pope, Patriarch and the other two leaders are doing at their meeting.
