[Quiet Man Cometh]

Is it the destruction that is the issue? I wasn't sure if it's part of the Valar/Maiars interested to interfere in happenings on Middle Earth outside of the Havens/Undying Lands etc (not sure if we're talking the same thing with those or not). I guess part of it is my wondering how much the Valar et al. really care about the people. Some of the elves certainly weren't all that fond of the Valar and such. Would there be any obligation or inclination on the part of the Valar to go beyond making a safe place and ushering people there if they want to come?
