This sentance made me jiggle, I'm sorry. Let me take it apart please. Firstly, let's divide your sentance into two parts, first part are the refugees, and second part is the greatest enemy.
1) Muammar Gaddafi said on camera in one of his interviews, that strong Libya prevents hundreds of thousands of refugees from Africa entering Europe, and fall of Libya will result in terrorism in Europe.
2) North Korea is an isolated political island surrounded by sea of sanctions. I just do not see North Korea posing a threat to anyone, whether it has an H-Bomb or not. Indeed North Korea is a comical threat, a boogey man that the big brother has created to keep you scared and ****ting in your own pants.
With one and two in mind, let's ask now, what country caused the refugee problem in Europe? The correct answer the United States. The United States is responsible for refugee problem in Europe. The United States is lying to you about boogy men, they lyed to you about Gaddafi and they lying to you about the danger that the North Korea poses. They are lying to you about this in order to shape your opinion and to make you support and do evil stuff in the world, which in the long term shapes the world in favor of the United States.
Germany is a powerful European economy, it needs Russian natural resources, and Russian markets for sales. United economically, Germany and Russia are an unstappable force (by US own admittance), which will control Europe and force the US control to deminish in Europe. The best way to destroy enemy fleet is to not let build your enemy a fleet, as we all know. Thus the United States creates wars, economic instabilities, and other political disasters across the globe, in advance, to achieve its own global dominance.
The United States needs you, the people of the United States, in order to achieve its national (corporate) shadow agenda. The United States needs you to obey, and not be able to stand up and take arms. The latest gun law is just an example of pre-emptive strike of your out of control government against its own people.
