Mysteron Intentions?

[ffutures]

The theme song for the original Captain Scarlet series includes the line

Though the Mysterons plan to conquer the Earth,
This indestructible man will show what he's worth...

Except that I don't recall the Mysterons ever expressing any intention of conquering the Earth - their goal always appeared to be revenge for human aggression after they were brutally attacked by the first Mars expedition without any provocation. So pain, death, etc. yes, but conquest no.

Am I right about this, or is there something I've forgotten?

They never seemed to do anything that could be seen as a prelude to conquest, just apparently random terrorism. Given that they were always working through mind-controlled puppets the logistics would be very daunting - especially once the human governments got their acts together on e.g. Mysteron detector machines at key locations. I can't see many governments refusing to expose the population to an occasional x-ray if the alternative is Mysteron infiltration.
