Putin said that Russia would take a 'principled position' once it got 'objective, precise data' on who alleged chemical weapons use in Syria.
Depends on who you ask.
President Obama's decision to seek congressional approval and global support for a strike against Syria is laudable. But the US – and Mr. Obama – might have to go it alone. Chemical weapons are in a terrible class by themselves. The world must maintain its taboo against them.
Congress appears split about a Syria strike, making matters difficult for President Obama. But even if Congress approves, Obama has taken an unusual step that could weaken the presidency.
