North-Korea has attacked South-Korea

Shame we don't have one of those indestructible super sized domes made of a clear polycarbonate nano-tube resin that we could just lift and drop on top of the country sealing them off from the outside world forever.

That's an incredibly ignorant statement to make, and it doesn't sound like sarcasm. There are plenty of good people in North Korea, and many of them are smart enough not to fall for the state propaganda. You don't think they protest? You don't think they die for trying to fight for better living conditions? Do you believe they like the fact that their government does stupid sh!t that results in more sanctions and at the end of the day, they (the people) are the ones who pay the price? They are hungry and due to North Korea's terrible economic policy, they function on meager jobs. Of 190+ countries, North Korea is at rank 154 in terms of GDP (purchasing power parity). That means the average citizen only makes 1,900 dollars a year. Make them even more insular against their will? That's plain sick.

By that logic, Africa would be sealed off from the rest of the world due to all the guerilla/civil warfare. Not a fan of that kind of thinking by any means.
