Wrong. They do respond to recursive queries. They just don't iterate
to find the answers for them. You either get a referral to the name
servers for the relevant TLD or the correct answer if the query was
for something in the root zone.
I just sent a query with the rd bit set to a.root-servers.net
(your favourite root server) and got a perfectly valid reply.
% dig @a.root-servers.net . soa
