No you haven't won the argument. You essentially said all my concerns and points were irrelevent.
I asked how do we prevent the conflict, your answer was that we don't have to
I asked how do we prevent the use of nuclear weapons, your answer was we don't have to
I asked what do we do with the millions of refugees, you said nothing
I asked how do we deal with the public image issue, your answer was nothing
So you have essentially dodged every point I have made by flippantly denying they are problems, when they are.
