My interest in the cold war comes from having grown up in a place that had one of the highest ratios of nuclear bulls-eyes to human beings in Europe. "The Great Belt" is a deep (75m) narrow strait (20km) which would have been the soviets only chance of getting their baltic fleet out, the other two straits are small enough that they could be efficiently mined/blocked. Already then, we knew that both sides would have the strait in their atomic target lists, only later did we find out how very very certain they wanted to be. The trick is to be able to apply what you learn from one interest to productive uses in other interests. Poul-Henning PS: Interesting historical tidbit: The observation that missiles were on their way to Cuba came from the island Langeland in The Great Belt. If they hadn't noticed, the US blocade would have been too late and the world probably quite different.
