Should we intervene on the Gaza Strip?

The Gaza Strip conflict has been one of the longest lasting conflicts; as it seems that the problem is not going to cease, should developed countries intervene in the zone in order to help Israel and Palestine to get into an agreement?

The war in Gaza is very important because both the United States and Russia are involved. This conflict must end once and for all and that both parties (Israel and Palestine) reach a consensus with the help of the UN as an objective and impartial organizer to ensure that both parties come out on equal terms, since as we know the territory of Palestine has diminished in a huge proportion and these territories taken by Israel must be returned. On the other hand Palestine must guarantee that there will be no attack on Israeli territory; these would be possible solutions for the termination of the conflict.
