The good news, which is not often publicized (precisely because it is good), is that scenarios in which military spending is higher, the same, or lower in the future suggest that the high military costs of the twentieth century have been turned into what looks like a permanent peace dividend. World War I cost about 20% of global GDP, and WWII cost almost twice as much.
不太被公众了解的好消息（之所以如此，只是因为这是好消息）是未来军事开支会更高、不变或更低的情景都表明，二十世纪的高军事成本已经形成了类似于永久和平分裂的局面。第一次世界大战造成的成本相当于全球GDP的20%，二战则还要高出一倍。
