On page B13 of today's WSJ (Informed Reader), Alasdair Roberts (quoted) noted the paucity of sacrifices that Americans are making for the war effort. (Who do you think is undermining it?) "Even after January's surge of troops to Iraq, the U.S. has fewer troops there than it did in Japan 10 years after World War II." Perhaps causing this, Bush has not asked the American public or politicians to be a little selfless.
Given that 96-98% of greenhouse gases are caused by non-humans (see "Another reason to doubt climate change models" post), I'm not so sure we should go about making victory gardens as the WWII generation did.
