Well tbh, I sincerely believe that we should treat the problem from its roots always. aka, Islam. Military action will result in what? more media propaganda against us, and it will only give us more time. If they are building nuclear weapons right now, and we destroys it all, what makes you so sure that they will not rebuild it again? and again?
I agree its a tough situation, and their heads can be more stubborn than a stone, but military action will achieve nothing but hatred, victims of war, costs a lot, and you name it...
We must at least do our best to try and preach to the whole world the truth about islam, why its a threat to the entire world if an islamic country ever possessed a high-technology weapon, that should be our first step to world peace.
