WWII and its impact on food advertisement

After Alex's presentation today about the impact of World War II on the production and availability of food and therefore on the advertisement of it, I went back to an advertisement I found in a 1945 issue of Good Housekeeping. I decided not to use it in my presentation because of time purposes but I remembered this advertisement and how a small paragraph at the bottom confused me. Now, because of her presentation, I think I understand!

The small paragraph seen in the bottom right hand corner of the picture above says "Soon again, we hope - Because of the Government's tremendous need for cheddar cheese, these two famous Kraft varieties have been missing from your food dealer's display. But soon again, we hope, civilians can have Kraft American..." Unlike some of the advertisements that Alex showed us that specifically said something about the war or soliders or perserving food because of the war, this one referred to "the Government" needing food and called the viewers of this advertisement "civilians" which I am assuming is to contrast the soliders who were fighting in the war. 

I thought our conversation about the fact that food advertisements today don't include issues of our current day war was quite interesting. I wonder why not. Why are we so disconnected from a war our country is fighting?
