Various points, since this ties to a long running debate earlier in another thread:
Power has changed in meaning people: to assume the world in 2040 will work as in 1940 is as wrong as assuming the world in 1940 worked like the world in 1740.
Iraq is a good example, as are Chechnya, and the Occupied Territories; Modern states have immense military power- we can devastate like never before-BUT full devatation has become illegitimate: Back in the "good ol days", if say the emperors of old had had the weapons we do today genocide and mass murder would be common place- an area won;t surrender? We burnd down all their cities and villages, execute EVERYONE (or kill all the men, enslave eveyone else) and if we think people are hidding in a forest- set it ablaze, kill people as they come out. Or just gas everything and kill. Today only dictatorships dare do this (like Saddam vs. the Kurds), and even they deny doing it to everyone else. So, while states may have huge military power, it becomes less and less usefull at forcing people to do what you want politically on the ground, since the threat of mindless murder has vanished. You can tire people out, but if they are really determined, you don;t actually put an end to anything.
Militaries today are "expensive". I say that in quotes because almost no state today spends as much on defense as they used to do in 1740, when the King's army was the largest expense of the state-today even the US spends under 5% of GDP on it. Of course, spending much more than that for any large state becomes useless because: 1. If you intents are purely defensive, nuclear weapons, once developed, are the cheap answer- enough of them, and only a suicidal fool would attack. And if your intents are to project power, you run into the issue above. States might be able to then have enough power to destroy the military of another, but then have less ability to follow up by imposing political will. So, states might be able to deny others a certain objective, but the ability for on great power to force another one all the way down is rapidly fading.
So, when examing the future, we can;t act as if the changes in the forms and meanings of power haven't changed. They have,significantly.
