I've always imagined the war as one being deliberately held in a sort of WW1 trench-warfare state, without the possibility of breakthrough. The only weapon system I recall (and it's been a LONG time since I read the book) was the "floating fortress" which would seem to underline the supremacy of defensive measures.
Given the delicate balancing act a nation would have to undergo to maintain the literally most basic standard of living for its people while actually (and, of course, in the book, "actually" is a question) at war, I can easily imagine an "accidental" breakthrough on some distant front throwing off -- or threatening to throw off -- the entire delicate balancing act and true 3-way global war ensuing.
Just a thought.
