Actually, it's one interceptor per missile. All you have to do is to increase the range on the interceptor and it's booster so you hit the missiles before they debuss. And we are developing MIRVed versions of the GBI, so that one booster can put into orbit multiple little homing kill vehicles.
That technology is still many years away.
Into the next decade, a single nuclear weapon will be cheaper than a single interceptor -- meaning that Russia could match, then exceed, American numbers.
Actually, it isn't. With ABM you're no longer quite sure that your missile will hit it's target. Even a very thin screen presents innumerable problems for a targeteer.
As long as the Russians fire one missile for every interceptor, and then some, they will continue to have deterrence capability.
The C3I for controlling those missiles isn't cheap. By contrast, C3I for an interceptor is pretty cheap, since they're non-nuclear now, and who cares if one accidentally fires?
The electronics that guide a nuclear missile onto its target can afford less precision than those that guide a kinetic-kill device to a ballistic object.
A peacetime, expeditionary, conventionally-equipped large Army is a tool that will keep looking for a solution.
Like Mengsk, you wrongly situate motivate forces with the army, rather than with politicians. The key is not to create an Army that lacks certain capabilities in order to preclude certain outcomes; it is to elect better leaders and demand greater accountability.
The Eisenhower military was constructed to bolster a legitimate strategy: nuclear deterrence. What strategy does a "light" military enable?
The air war against Serbia in Kosovo was far less effective than originally touted. Even Desert Fox left a lot to be desired in 1991.
You are essentially telling us to abandon all ability to act as we did in, say, 1991, as a knee-jerk reaction to 2003. You claim there is no evidence that "adventurism" pays; what is your evidence that a "light" military works, or that isolationism will turn out to be a successful strategy? You don't have any, and you can't make any. We need a force that is prepared for all types of threats.
