Having followed this subject for a long time, and having participated in
debates on both sides of the pond, I can only urge that the US stops
thinking nostalgically about IPv4. Every debate and every article about
IPv6 adoption ends up focussing on IPv4 decommissioning, which is not
the challenge in the short term. In the short term, we need to get our
resources to run in dual stack.

To the question "Can we get out in time?", my reply would be "no, we're
already too late" - at least, that's the feeling we all got at the
EURODIG (European Dialogue in Internet Governance) conference last week.
Draft report on:

The time for IPv6 update is "right now".
