It's not the right time to develop a large fleet of interceptors, that's for sure. China loves trading with us, and Russia is just doing what Russia does (making good vodka and trying to make something of itself, both noble pursuits in my regard). Europe is becoming almost one big country, and South America and Africa just don't have the time.
On the other hand, we are slugging it out with bands of elusive freedom fighters, insurgents, terrorists, or what have you. The point is, we need lots of information on them, and to be able to deliver 'surgical strikes' without harming the surrounding populace.
