Eh Obama's constant drawing of lines then running away when calling his bluffs go beyond imperfect solutions to bad conflicts.
Do you really think any of that is going to be really memorable? For the past eight years the world has muddled along. Consider, when Reagan is mentioned how often does 'invaded Granada successfully' come up? Of course not. Of all the things that happened during his term that is barely a blip on the radar. When Clinton is mentioned does 'bombed Libya' immediately spring to mind? Not usually, and the sorry fact is that Clinton really didn't do much of anything that is all that memorable. For a foreign policy event to enter 'legacy' status takes a lot more than the world just muddling along.
President when the USSR collapsed. That's a legacy.
Orchestrated a world spanning coalition to repel an invasion by a larger country on a smaller country, with minimal losses and without continuing on into 'war for profit'...demonstrating that the concept of 'united nations' actually could work. That's a legacy.
First president to lead American forces into an unprovoked war of aggression, and dealing a death blow to that 'united nations' concept. That's a legacy.
Obama's foreign policy will be obscure trivia by 2020.
Being the president who got healthcare done may not be a positive for his legacy if the costs blow up and it continues to be unpopular. That is a large question mark.
Well, the thing about
legacy is that it is by definition a historic view.
Putting healthcare reform into a historic view doesn't allow for the currently popular pretense that the healthcare system in America was the greatest thing ever right up until Obama came along. In fact the preexisting system was about to blow up in our faces, and
everyone had known it for the past fifty years. The historic view is going to acknowledge that 'costs blowing up' is an unavoidable result of the demographics of the baby boom generation aging, not a result of Obamacare.
The historic view won't avoid the reality that even if Obamacare does nothing more than mitigate the disaster it will have succeeded, since the disaster has been seen coming for over fifty years, the pre-existing system could not have even begun to cope with it, and nothing else had been done to mitigate it before. Even if that mitigated disaster is still so bad that it leads to the collapse of the nation, historically there will be more questions asked about why Nixon didn't deal with the problem when he pointed out that it was coming. There will be more questions asked about why the reform didn't get done during Clinton's term, since by then the disaster was thirty years closer, still totally predictable, and he made a clear effort to do something about it but failed miserably. If it turns out to have been too late there will be more questions asked about every administration in between as to why they did nothing than will be asked of the one who did.
