Actually, the phrase "national security" is barely used until the 1930s. And there's a reason. By then, the United States was beginning to become global. Before that the United States had been mostly a regional power - Britain was the biggest global power. After the Second World War, national security is everywhere, because we basically owned the world, so our security is threatened everywhere. Not just on our borders, but everywhere - so you have to have a thousand military bases around the world for "defense."
Noam ChomskyI should say that Canada is one of the major criminals, not just the tar sands and so on, but even mining throughout the world, a lot of it is Canadian. It's extremely destructive, so an important thing for Canadians to do is curtail the predatory and destructive behavior of their own government and corporations. A carbon tax is one way of doing it.
Noam ChomskyIt is only in folk tales, children's stories, and the journals of intellectual opinion that power is used wisely and well to destroy evil. The real world teaches very different lessons, and it takes willful and dedicated ignorance to fail to perceive them.
