Even during WWII people were starting to get sick of the war towards the end.
And unrest war beginning to develop among the GI's from the European theatre when it appeared that they might be sent ot the Pacific.
Nuking Japan is very likely to have saved us problems here on the home front.
WHile it is little consolation for those who have lost loved ones, there were five times the number of Allied casualties on D-Day (one day!) that we have had in the entire Iraq war.
Maybe we should remember 9/11/01! Some people seem to have forgotten.
As for the general population, this is no hardship, our lives have not been as greatly changed.
Prices of some things are up, but we have no rationing now (unlike WWII).
A fraction of the people are directly involved in the prosecution of the war, with a small fraction of the number of soldiers serving.
We have not quit making new models of automobiles for the public, (check the model years, there were 1941 models, and 1946/7 models, but there were not many 1942,3,4,or 1945 model cars.
Everything was about the war effort, from rationing to scrap drives. (BUY WAR BONDS!) Even books were printed with special typesets and cheaper paper as part of the war effort.
Most people nowadays do not even personally know a soldier involved in the fighting in Iraq.
If we are "war weary", then we are truly just a faded shadow of the generation which grew up during the Great Depression.
