North Korea

There are very few countries that have stayed at war for as long as North Korea. The war originally broke out between two main groups in Korea, one based you guessed it in the North, and supporting the Communist Party that reigned supreme in the USSR and many other countries, and another group based in the South, that supported the old ways. The war last for around three years in the 1950s, and it only carried on for so long because the strongest military in the world at the time the USSR and China together supported the Communist rebels in the North. When it became clear that not even the most powerful army in the world could win the battles, an armistice was signed . . . but a peace treaty was never written, and that means that technically, North Korea and South Korea are still at war! Although North Korea does not have much to boast about with regards to its military, it does hold one world greatest record: North Korea has the biggest number of submarines. They have almost eighty! It may seem a little strange that they have invested so heavily in just one kind of global firepower, but you have to remember that South Korea only has one border: with them. The rest of it is surrounded by the ocean, so if you wanted to spy on them, then submarines would be your best bet.
