Antarctic union

The two jets paused above and began to hover in place, observing the ships. The man talked slowly
"Shields? I'm a civilian, I don't even own a damned vi..." He stopped his little rant short, regaining his composure after having been shaken by being faced with a war fleet "America... Of you're going there, prepare to be destroyed. America isn't a place you want to be anymore... Hold on..." He turned to the front of the boat, bringing up the touch screen navigation and pulling up a political map, he tapped a few times on the screen, then placed a small piece of metal against the side of it. He turned, and yelled "Catch!" before tossing it up to the boat. "Hopefully that's compatible with your computer systems... Got the location of the Empire of America, it's in blue... You are at the bottom of Africa, the Commonwealth land is all Red, key's along the side, The moon and mars holdings of the nations are included in the second segment... Usually you'd click the countries to bring up a fact file and recent history for the past century... but... Given systems it might be wise to open their individual files rather than chance compatibility. No need to pay or anything just... I have no idea how long you've been away, but the world is obviously a lot, lot different if you are wanting to go to America..." He paused "Apart from some trade ships, which even then are few, most people don't brave America anymore, its nearly as dangerous as the Fourth Reich..."

Commonwealth action

The Commonwealth has embargoed the Yugoslavian Empire and their allies in the Fourth Reich and threatened war with them should they not retreat to their own borders and drop all claims to land outside their own. The Commonwealth has moved some of its forces to the borders. Several nations have requested assistance, including Egypt and Portugal, and the coastal African nations, including Morroco and Egypt Due to the importance of the Spanish buffer, the commonwealth has stationed forces there with agreement of the Spanish government to reinforce the Spanish against any foreign powers. In addition, the Navy has blockaded the straits if Gibraltar, slowing supply movements to Yugo forces beyond the straits. Commonwealth weapons have been found in the hands of African and European soldiers fighting for their countries, and the Commonwealth has given assistance to them through funding. The Commonwealth has proceeded to use its security network in an attempt to locate any dissident factions within their opposition in order to offer them support.
The Commonwealth has began planning for "Operating Falling Angel" as well, and have announced that they are willing to offer protected status to any nation fearing foreign invasion... And its quite clear what they mean by "Foreign invasion". The Commonwealth has presented an ultimatum to the opposition

-Withdraw to within your own borders
-Drop claims to nations you do not own at the current time
-Commit to assistance in paying for the repairs of the damages your invasion has conflicted
-You have 24 hours to comply.
