I'd say they hardly explained anything.
What do we know?

1. At the beginning of Saikano, the kids say they are bored because of no tv no cell phones no internet, all of these have been banned, it's a first signal something is really wrong but I think most hardly noticed it when mentioned.
2. The war begins with the air raid on Sapporo (I think it was Sapporo) by unknown troops, whoo then are taken out by Chise
3. All we know after that is that Chise is some kind of last resort weapon and that there is indeed a war taking place.
4. It is mentioned that Tokyo and Oosaka have long been destroyed.
5. We find out the enemy speaks english and that it's appears to be a war for survival of the species rather than an actual war of conquest.
6. Chise whipes out enemies by annihilating lost land.
7. in the end everyone and everything dies/is destroyed.

I may have forgotten a few things left and right but I think there are still alot of unanswered questions, not that those really bothered me since the anime was not about the war but about Chise and Shuuji's relation.

well, in the last couple episodes, Chise explained that

Spoiler for ending:

human history is a history of war and pollution, and after a long history of humans destroying the nature with wars and pollutions, finally Earth itself reaches its limit and is about to die. Basically there are less and less natural resources and inhabitable environments, so everyone is fighting for the last remaining resources and inhabitable living places, which depletes the resources and destroying the environments more and more, a vicious cycle that accelerates the death of the planet. So in the end the world outside of Japan becomes terrible and uninhabitable, so everyone is trying to inavde Japan for the last habitable place in the world, and in the end the only habitable place in the world is the town protected by Chise. But as people outside make a final attack on Chise's town, the planet itself at last dies, and Chise can only save Shuuji by merging her immortal body with him, thus granting him immortality so he can live on on this already dead planet.

As for the ban on TV, internet, etc. etc. it's to cut off communication to the outside world, thus hiding the fact that the entire world outside of Japan has already died and become uninhabitable, in order to prevent mass panic.

So I think the TV series has explained it quite clear already.
