This could get interesting real fast.
How much territory can Hussein give up? If the Russians and Chinese are aggressive enough we can be pushed right back to our North American borders, borders which don't really exist.
How would we receive a couple of million Chinese troops in battle dress and armed flooding across our borders as "refugees" and undocumented immigrants just looking for jobs and a better life? Would Hussein tell ICE and the Border Patrol to "stand down?" Would the government strive to resettle them in strategic voting enclaves in Conservative states?
