Cautiously and reluctantly, but inexorably, President Obama is teetering towards US military intervention in Syria. He knows that nothing good will come of such intervention; yet, even with the examples of Iraq and Afghanistan, he appears unable to stop the maxhine. He also knows that getting in will be considerably easier than getting out. And he must be conscious of the difficulties of finding a form of intervention which will avoid making matters worse for the ordinary Syrian.
That is not to say that the Assad regime is remotely acceptable, even if there are other regimes in the world that are equally despicable. Nor can I deny that the Syrian rebels deserve assistance, even if they have some dubious allies in the fight.
It may be a counsel of despair, but some issues are just intractable. And perhaps there may come a time when the US has to recognise its limitations and stop playing the global policeman.
