Don't think that we're the most powerful country. I have a friend that works with DOD and NSA as a computer network security consultant. Let's just say that their computer systems have actually been shut down WAAAAYYY too much already this year by foreign governments. You remember that blackout up in NYC? Supposedly that it was the result of a certain Asian government. The power companies were working with an Internet based way of checking power meters when they were hit. It was a virus. The virus that actually did that had 33 different styles of programming in it. One part of the code would execute and make way for the next bit of code. It was a brillant piece of work. If someone wanted to take down the USA, all that would be needed is an internet connection. Can you imagine if the US lost power like that again? You don't need to have a larger or technologically more advanced army to win a war. You just need to know how and what to hit.
