The Celtic Alliance is a monarch-run country in the Greater Isles, and is bordered by French England to the south, the North Sea to the east, and the Atlantic Ocean to the west. The Celtic Alliance has the world's fifth largest economy, and maintains control over the oil deposits in the North Sea. The CA was not hit as hard as some countries after Peak Oil was declared.
The Celtic Alliance maintains the sixth largest standing military and has a "No Nuke" policy, stating that nuclear weapons, nuclear materials, uranium, and/or nuclear waste can not be shipped through Celtic territory. The CA is a founding member of the United Nations, and is more aligned with the US, as France continues to pressure it into sharing its North Sea revenues.
