When bosch realized his NTF was about to be crushed, he set up a communication post in the Alpha Centauri system, to commincate to Earth. Even though all contact was severed with Sol, radio messages could still be sent. From Alpha Centauri, the nearest star to Sol, the messages would take 4 years to arrive.
Bosch told the Earth about all that's been happening in GTVA space, and about his rebellion. Bosch communicated his true objectives to Earth, as well as the plans for the Knossos device.
The Earth got strong to Bosch's ideologies, and formed a new NTF, bent not on the extinction of the Vasudans, but to work towards the final alliance with the Destroyers.
Ever since the end of the Capella Battle, the people of GTVA space fell into an era of great depression. Their prides and hopes of victory over the Shivans were devastated when they learned of the enormous J-Fleet, the fleet of juggernauts. The depression caused the whole of GTVA space to fall into anarchy, with each man striving to get his share of power in a world that was doomed already.
The Earth's NTF anticipated all this, and decided to re-open the Sol Jump node from their side, and end the anarchy to establish a thriving civilization to enable the alliance on which the fate of humanity depends...
And so the next chapter in an old war begins.
