Israel-Palestine: R2P

A domestic issue with international side effects is a global issue.
The current situation governing Israel-Palestine cannot be found merely domestic issues of these parties. The dispute of Israeli and Palestinian states itself has been the origin of a few wars and emergence of militia and terrorist groups in the region, which are threats against all. 
The continues violation of human rights and humanitarian law by third parties like Hamas and Hezbollah under the shade of the dispute is now identified a constant parameter in this regard. Therefore, the world community and the major Arab states have this right to take advantage of all means to settle peace by invoking the principle of Responsibility to Protect. It is evident, the principle would legitimate any essential decision on behalf of Palestinian nation by the world community if the Palestinian state fails to accomplish its part. 
At the end, the model of multilateral negotiation among Israel, West Bank and the GCC is recommended.

Today, Tehran suffers from such a disease. But this situation cannot last as an opportunity for good. The wave of public discontent will eventually turned into the feeling of frustrated that would lead to social collapse and chaos; The situations of Cuba and Venezuela, for instance. 
Therefore, an accurate planning for launching a revolution or coup Iran can make the idea “regime change” possible.
