Israel needs to concentrate with the PA and not Hamas. It is not reasonable at this time to expect their acceptance of all the 3 conditions by the Quartet because the main focus is the PA-Israeli negotiations and Hamas agreed that President Abbas lead the talks on behalf of the Palestinians. Perhaps in the near future, Hamas and the other factions will not only change their ideologies and activities of violence, but will articulate Israel's existence in the ME after the PA signs a peace agreement on behalf of all Palestinians. Hamas is not ready. How can an addiction to violence and destructive behaviour against Israel be transformed within months ? It's not really reasonable for Israel to focus on Hamas changing politically in the near future and therefore indirect relations are at best achieved through the PA and Egypt. As long as there is quiet in Gaza, Israel has to focus on the PA and not Hamas at this time. Hamas's contribution now in exchange for quiet is more quiet during peace negotiations. If there is a relapse, then not to over-react and encourage the quiet for the sake of relations in the future. I think that's how it will work.
