OK. I am unhappy with you because you ( seeem to) support people who want to murder people like me.
Well, I accept that there are people in the world whose grasp of reality is essentially non-existent, as yours is, but they cannot destroy the world. A large nuclear arsenal is needed for that.
How will you make me happy? Support the Wall in Israel, to keep them out? If you do that, the Palestinians will be unhappy with you.
The only way to make you happy would be for me to kill all of the Arabs, Palestinians, and Muslims in the world. Obviously, I can't and wouldn't do this. But that's why we need the world court. We set rules that are applicable equally for everyone, and then we apply them. In your case, and that of Israel, since the settlements in the West Bank and East Jerusalem are illegal under international law and according to treaties that Israel has signed, the court would rule against Israel and, while Israel could still put up a wall, they would have to do it along the pre 1967 borders. Now, you might not be happy about it, but you wouldn't have the capability to destroy the world because of it, and even if you killed as many people as you are physically capable of doing, the law has provisions for people who commit such crimes.
You ignore the fact that there are people in the world who hold opposing opinions. YOU CANNOT MAKE EVERYONE HAPPY.
Exactly so. Which is why your system cannot work. You are relying on a missile defense system to prevent the destruction of the world, which you have said will happen if even one WMD is delivered. And you yourself have said that it is not possible to prevent all WMD from being delivered. So therefore, you are advocating a system that is no more effective in preventing the destruction of the world than MAD. The only way to do that is to eliminate the nuclear arsenal, and to have a system of international justice that ensures equality before the law for all of the peoples of the world.
