This is a major strategic challenge affecting not only our military, but ultimately, America's leadership in the global world order, we are at a point where our national aspirations are at risk of exceeding our available resources.

If there are threats to the United States, then I would of course go back to the president and make a recommendation that may include the use of U.S. military ground force.

We do have treaty obligations with our NATO allies.

You might argue that we have become a little too forgiving because, if a perpetrator shows up at a court-martial with a rack of ribbons and has four deployments and a Purple Heart, there is certainly the risk that we might be a little too forgiving of that particular crime.

We do have an obligation to deter conflict and to prepare for it should it occur.

I think what happened is, we have gotten a little careless maybe and sloppy over the last 10 years with the mechanisms that used to provide oversight, checks and balances, a safety net, if you will, for professionalism.
