In the interest of adding two cents on Syria, I quote the admirable Andy McCarthy, who, thankfully, has done the heavy lifting to arrive at the all-important bottom line concerning whether the United States should become involved (NO). Having established the bona fides of the "Syrian opposition" as True Enemies of American National Interest equivalent to Assad  -- just look at the oppo and its boosters, from the Muslim Brotherhood to Qaradawi to Zawaheri to Hamas (to those diehard "Arab Spring" enthusiasts at the Foreign Policy Institute and Foundation for Defense of Democracies) -- McCarthy writes:

When America’s enemies face off against each other, it is not in our interest to choose one over the other. As they battle, they weaken each other — and that has already had the salutary effect of weakening Iran, which now sees not only Assad teetering but its tenuous ties with Hamas fraying.

Of course it is tragic that some innocent victims and authentic liberal democrats are caught in the carnage. It is not our burden, however, to prevent that or to become enmeshed in other countries’ civil wars – not when there is no vital American interest in one side’s prevailing over the other. It is certainly not in the vital interests of a country weary of war, out of patience with Muslim madness, and $15 trillion in debt to further insinuate itself so that anti-American dictators can be replaced by anti-American Islamists.

It’s a pity that they can’t both lose. But if they have to savage someone, better each other than us.

Wise words. Having "achieved" no more than what McCarthy calls a "sharia ascendancy" across the Middle and Near East since 9/11, the US can't afford any more such "success."
