Hmmm, an interesting challenge: To protect the lands of Men we need military power and lots of it, I'd say! Therefore it is imperative that we remove those Elven lords who'd prefer to sit in their marble halls and drink expensive wines while watching young elf ladies dance before them, while the poor Edain are being slaughtered in their mud hovels. Therefore I'd say we should remove either Turgon or Thingol, the two prime isolationists of Middle-Earth. This would also allow their daughters (either Idril or Luthien) to ascend to the throne, giving the male-dominated Elven society a much needed feminine touch. I'm sure these powerful, strongwilled and active ladies will waste no time in sending military forces to protect the Edain. Therefore I'd say:
++ Thingol
Though Turgon is fine with me as well.
