Well I had to find the interview on YT since I hate QT...from my unpolitical viewpoint it didn't seem like he was 'making pathetic excuses' - he says several times that he didn't get him and that he regretted it and trying to explain the events or reasons for failure doesn't seem pathetic, it feels reflective and acknowledging that he's only one man and sometimes timing, political atmosphere of the day etc. combine to equal certain results, good intentions or not.
That said, it also does appear to me, only from watching the interview, that he wasn't surprised into his verbage by being 'jumped on' right then. So while Clinton has a gift for speech and analytical thinking (most of the time...) it seemed obvious that Clinton had the agenda of saying what he said from the get go, maybe in reaction to other things, maybe as a political influence move, whatever - which feels a bit petty or manipulative, if that's the case, even if it's fun to watch.
I'd have to agree that there is no single blame factor & the 'armchair blame game' is usually unproductive. I doubt many of us could do better when out of the armchair and faced with political decisions that are not typically made/created by a unilateral/lone-ranger process.
Edit: grammar again, argh
