I know it seems daunting to win, but keep in mind, our enemy's soldiers are retarded and killing themselves off with the shots, degeneracy, disease and other maladaptive behaviors that lead to failure and death.

Yes and this is why they make sure before they go down they take 4 billion. The control grid they established worldwide is virtually impossible and they know it. What they are doing now is to kill as many people as they could before they get brought down, and as long as they murder 4 billion, leave most survivors traumatized and make sure the whole situation is completely irreparable they already won.
