The 2nd Goner Invasion Gets Rekked

Military action

The Goners are defeated!

---

The destruction of the Mars base means that the individual Goner forces on Earth have to operate alone and, one after the other, they're defeated.

Greenland: The Goners here run out of food and are stuck due to the weather and damage to transports and resort to eating the inhabitants of the land, followed by one another. The last of them are sweeped out by a mixture of lots of Greenlandic militia and some Danish troops.

Siberia: They split their forces to attack Alaska, where the militia forces have to fight a guerrilla war. The USA sends a massive force through Canada, which Canada manages to mistake for an attempt at conquest as they don't know about the Goners yet and the USA was talking to itself rather loudly about conquering Canada over the last 15 years... the Prime Minister of Canada surrenders to the USA when war hasn't even been declared and, despite attempts at saying "no we made a mistake let us go" the USA would just giggle for a long time to come.

Meanwhile the ones in Siberia hold out defensively against Russia and invade South into China, which is busy at the moment with the Goners that landed in Australia. Due to this, China looks at Japan's new super-advanced armies, which contained some robots, with puppy eyes and Japan responded with "hippitty hoppitty you're my property" and defeated the Goner forces on both sides of China.

Australia: they advance through tonnes of islands and into Laos, taking over the rest of Indochina from there. They slam India and China pretty hard but then Japan comes along and, teaming up with India, destroys the Goners all the way back to Australia.

Southern Texas/Northern Mexico: militia and guerrilla forces are able to suppress the Goners enough for them to be forced to only advance South, being constantly worn down by Mexican and Central American forces. By the time they started advancing Northwards again, taking most of the ex-Confederate USA in the process, the USA and Canada's army has shown up with the "fuck yeah, America" and "FRIENDS theme tune but with Canadian shots" songs playing at full volume and utterly smashed the Goner forces.

Argentina: they do the best by taking a whole continent but are so damaged by guerrilla warfare with South American forces that the USA and Japan have an easy time splitting it in half between them.

Antarctica: The United Commonwealth owns Antarctica. This matters because The Arctic/Antarctic War was a thing.
