The problem is that the offered solution to the conflict (2-state solution) is horribly wrong, and will never work out in the long-term. The only way to solve this conflict is with the 3-state solution (http://en.wikipedia.org/wiki/Three-state_solution).

So first, they need to have a proper solution in mind, so that everyone agrees on a trajectory for negotiations, and then do whatever they can to end the conflict. The thing is, whenever talks of a 3-state solution start, the other Arab nations show us that they don't really care about the Palestinians because they tend to reject it.
