A worthy question

From the comments section of this Washington Post article:

How does killing Syrians horribly with cruise missiles demonstrate care about the "innocent people dying horribly from chemical weapons"? 

Even worthier questions, leading up to Tuesday's Presidential address and this week's Congressional vote:

- What gives the U.S. the authority to 'punish' any nation that has not directly attacked or threatened it?
- In the event the Administration presses ahead without Congressional approval, how is that Constitutionally permissible?

And the worthiest question of all:
- If our 'leaders' commit us, yet again, to the fool's errand of trying to fix generations of sectarian strife in a time frame that fits America's short attention span, what will those of us who actually care about the Constitution and sound public policy do about it?
