We discussed recursive DNS servers before (servers which allow to query anything - including what they are not authoritative for, through them). ... One of the problems is obviously the spoofing. ...
Maybe I'm misunderstanding the problem here (but I don't think so). It seems to be the issue is not DNS -- recursive or not, but rather a failure to adhere to BCP 38. http://rfc.net/bcp38.html
One may get easier/larger amplification from a recursive DNS server, but the same problem exists for a non-recursive server. DNS, then, isn't really where the problem needs to be fixed.
You are right, to a degree.
