The Reason why Cheetoriah created a war against the Deer's Universe.

Because the Beaver's Universe elected someone who is not from a establishment. A Union democratic outsider who can create Jobs, especially with the squirrels needing jobs from the southern Cheetoriah Universe.

Unfortunately for the Neo cons of Cheetoriah, they don't like that. So they have to result to plan B. A Terrorist attack within and blame the Deer's for weapons of mass destruction.

As an Author, I feel sorry for the Deer's that can't catch a break.

At the same time, the Deer's started shit in the beginning way long time ago. The Deer's Universe become the biggest enemies for the Beavers and never forget. With all the Job loss the Beaver's accomplished in the beginning.
