I agree, but my point is that he can do a lot of things short of an outright military intervention that will make it all that much harder for NATO to invoke Article V when push comes to shove at some point in the future. Certainly we have provided a modest response to his provocations until now, but I would prefer some continued creative thinking about how to aggressively counter his moves without precipitating an armed confrontation. It should indeed concern us if we have an administration that ignores the problem, because when the next administration comes around, it might be too late to head off an actual fight.
