the whole cold war interesting too, and its really cool to see how it affects the world today. like afganistan is a prefect example. the SU, wanted to invade iran, and so they invaded afagnistan first so that iran would have to fight a two front war. teh soviets wanted iran so they would have land access to the indian ocean, that way they could build a base there and have a major navel presence in 3 oceans around the world. the US did want this cause it would gave the soviets a massive stratigic advantage. so they trained and feed weapons into afganistian, to halt the soviet advance. (funny how bin laden was one of those that were trained). anyway so the soviets fought and fought, then eventually after 10 years picked up and left, shortly b4 the collapse of the union. NOW the US is in there fighting the same people they trained, who are now using the weapons left by the soviets.
