World domination sci-fi scenario

[k von doom]

The population of the Earth has been replaced with:

Antarctica has 2000 Xenomorph Aliens
Australia has 25 million T-800 Terminators
Europe has 470 million Yautja Predators
Asia has 4.4 billion Chitauri
North America has 570 million Independence Day Aliens (start with 10 small spaceships)
South America has 420 million Starship Troopers Mobile Infantry (movie version)
Africa has 1.2 billion Ultron robots

All species begin with their standard individual equipment (armour & artillery for Mobile Infantry, guns for Terminators..etc). All territories are equipped with their real world natural resources and current technology for that region (i.e. Antarctica starts with only tech in the research stations and ice). All territories are blocked off by a magical forcefield for one month. This time can be used to plan or create tech. No interspecies alliances allowed. If a species has no means to create flight transport to engage in battle, after one month (and every month thereafter) a magical indestructible aircraft carrier will fly 100 units to the closest opposing territory.

Which species can wipe all the others out?
