The invasion of the United States by the armies of North Korea and China happened quickly - it was well coordinated. With satellites down and power grids out, America was unexpectedly knocked back on its heels.
After three months of brutal fighting, the battle lines within America stabilized, for the most part. Many states are now behind enemy lines and considered occupied territory.
Many foreign nations, thought to be America's allies, promised aid and troops... Ultimately, none came.
Now, America's war to rid itself of the invaders is waged by what is left of the US Military and America's civilian militias.
This war will be America's finest hour... Or it will be America's final hour.
