The atrocity of the Akallabêth

[Legate of Amon Lanc]

Once more to that "they didn't care for Men" part.
I'll try to write it shortly and clearly:
1) the Awakening of Men took place when there were enough problems with the Noldor,
2) Valar didn't even know the exact time of their awakening, and as Maca said, it was pure accident that Oromë found the Elves (Valar knew just "the time is slowly coming", but didn't know exact date),
3) and most important, Valar themselves decided not to intervene after their first "failure" - which is what they considered the assault on Utumno and going for the Elves to be. Melkor had by the time of the awakening of Men returned to Middle-earth, and Valar did not want to intervene to the Silmarils cause of Noldor, no other assault on Angband until a messenger from both the First and Secondborn came to assure them that both the Elves and the Men agree with, and request, their help. No other war which would tear land apart (although in the end, it is what happened in Beleriand), no Oromë coming for the Men - and as I said, they didn't know of them - because Valar didn't want to rule with fear (as opposite to Melkor), to force the elves to go to Valinor, to create an image of terrible power so that the elves won't love them as they are but out of fear. This is basically why they considered their behavior at awakening of the Elves as their "failure", and this is why they didn't come for the Men.
