It is clear that the US is prepared to fight another war - this one in Libya. True, there won't be any US troops on the ground - at least at the outset; I wouldn't expect that to hold if things get messy, as they tend to do in war - and the cause seems just. But isn't our culture growing too comfortable with war? Yes, the situation in Libya is already out of control and is already militarized, but does our nation's response need to be sending in men and women to put their lives at risk
Also - is President Obama unaware, as President Bush seemed to be, that we have a Constitution? It didn't used to be the case that the President could just declare war in all cases without the Congress being involved. Why isn't every editorialist and Congressperson in the country outraged at the President for this?
Here is a paper I wrote on Judaism and war. It is not quite on topic - my subject was Jewish teaching concerning the taking of civilian life in war - but there are some useful sources there.
