Salvation is clearly our best bet right now of pushing back the thargoids, we now know he has a lot of intel and resources and the will to do things none of the supowerpowers or Aegis had the guts to do. The question however is, if this prototype weapon manages to take down an entire fleet, then how will the thargoids react to this? Will this be the de facto declaration of war? Will they start to massively harvest minerals to fund their war fleets just like they did during their war with the guardians? Guess only time will tell, but in this case, i want to be on the side that has the big gun and that is without a doubt Salvation.
