While President Obama focuses today on the 50th anniversary of the March on Washington his administration is grappling with a very difficult decision on Syria.
The conflict there could expand.
Israel and other nations across the Middle East are mobilizing reserves and going on high-alert because of fears of a regional war.
The US and its allies are mulling the possibility of a military strike to punish the Syrian government for its alleged use of chemical weapons last week.
But huge questions remain–over the current lack of evidence of responsibility for the attack; and what legal authority there is for war.
Peter Beinart has his own question.
Beinart is senior political writer for the Daily Beast.
He wants to know: "Why is it worse to kill civilians with chemical weapons than some other way?"
