Dropping support for the .ru top level domain

I propose dropping support of the .ru domains as an alternative to the
other measures discussed here, such as dropping Russian ASNs -- which
*would* have the counterproductive effect of isolating the Russian public
from western news sources. Blocking those ASNs would also be futile as a
network defense, if not implemented universally, since the bad actors in
Russia usually exploit proxies in other countries as pivot points for their
Preventing the resolution of the .ru TLD would not impact the Russian
public's ability to resolve and access all other TLDs. As I noted, there
are countermeasures, including Russia standing up its own root servers, but
there are two challenges to countermeasure: 1) it would require modifying
evey hints file on every resolver within Russia and, 2) "other measures"
could be taken against whatever servers Russia implemented as substitutes.
Dropping support for the .ru TLD action may incentivize the Russian State
to bifurcate its national network, making it another North Korea, but that
action is already underway.
Other arguments are political, and I do not presume to set international
political policy. I only offer a technical opinion, not a political one.
The legalistic arguments of maintaining treaties is negated by the current
state of war.
