Your right, the cold war wasn't a war. Vietnam and Korea? They were just peaceful spitwad matches.
Afghanistan? What about Afghanistan? THERE'S WMDS IN IRAQ!!!!! Ignore that guy over there saying we made Bin Laden, if you don't you hate America because there is WMDs in Iraq and therefore terrorists!
And the Cuban Missile Crisis? That was just the Liberal Media making up stories.
Yes, the cold war wasn't a war. Countries weren't used as pawns in a power struggle. That was all an illusion.
As for economies, there are very complex issues regarding economies. Take, for example, Argentina. Look at that beautiful color of economic growth, 10%+. How wonderful, it must be the land of Milk and Honey. In fact, everyone in Argentina must be wonderfully rich! (GDP Per Capita $13,307 for Argentina, vs $43,444 for the united states)
Wars drive innovation though, for two good reasons.
1) Money and "lack of oversight" pour into research stations, and results are taken as the payment for such free flow of resources.
2) People who become absorbed by the conquering force usually become equipped with the same base as the conquerer, widening the base that the particular technological advancement is standing upon. Even those that manage to hold off still "capture" technology of the aggressors, allowing their technological base to increase to the standard.
Times of peace do appear to have many new inventions come out, that is true, but they are almost always refinements from war technology, and aren't the great leaps forward that come from the creative thinking that war requires.
The reason for that is pretty simple, Money is an object for corporations and "the free market", so the base of a new technology, the often unprofitable base of a new technology, is never developed. If it doesn't make someone a lot of money, it isn't done. Until the initial uses are discovered there is no way to make a profit out of it. Where was the initial profit in the Internet?
That is the story of all the base technologies, from roads to the usage of radiation.
