War - what is it good for?

San Francisco Business Times reports ten major California health-care organizations, including Blue Cross of California, Health Net, PacifiCare and Sutter Health have declared "war on fat". They will also try to recruite other organizations to make the program state-wide.

So, how will they fight this war?

Well, every health care provider "is expected to fill 50 percent of the space in vending machines at more than 140 worksite locations with healthy snacks and beverages, such as water and fruit"

Is it just me thinking:
1. Does it take a state-wide initiative to change what's in the vending machines?
2. Why, in a health care organization, wasn't the vending machines containing fruit and water already before this initiative?
3. Will it actually make any difference other than that the 50 per cent fatty stuff will be procured more often?
4. Is this a war?
