rebalancing our defense expenditures so we can put the necessary investments where the greatest need is likely to be. >> so just to understand where this is going, when we sort of thought of libya, as an example here. i know you were against u.s. intervention there. that was a case in which there were no u.s. boots on the ground but we certainly provided air strike support. general, is that a model for how war will resemble under this plan? >> well, i think it's clear that we've got lots of capabilities. we can intervene again if we have to to support others the way we did in libya. we can do much more if necessary. the air force, the navy, the army still will have substantial capabilities and we can act in more than one place at once. the truth is we're out of iraq right now. we've got a withdrawal schedule for afghanistan. so these troops that are coming out, these two major land wars, that's where we were. we need to look to where we need to be and where we need to be is to face different challenges.
