We could see the collapse of these 2 countries.

I'm sure many countries will collapse in our lifetime - especially many undeveloped countries. But here are 2 predictions for you:

In the next 5 years, I'm predicting the collapse of North Korea. Sure, they are an undeveloped country, but they've also been in existence since the late 40s, despite being shunned by the world. Well I think their time is up. They're currently suffering from another famine and many countries can't afford to send food aid because of the shaky world economy. Plus their "dear leader" is sick and may soon die. Look for North Korea to collapse.

Next prediction: Japan. This is a bold prediction considering they're currently the second largest economy in the world. I give them 40 more years. The big problem is that they're facing a HUGE demographic crisis. They're an aging country with a falling birth rate. Starting about 2015, they're population will fall drastically until 2095 at least. This is extremely bad news for any economy. Economies need growth and you can't grow if you're losing people. Most countries can fix this by immigration, but Japan is a deeply xenophobic country and net immigration is basically zero.
