Maria Zakharova (Russian foreign ministry) made this comparison, not so forcefully or directly, and I thought I'd just put it out there a bit more directly because I don't represent Russia so it can't be seen as a provocation or threat if I say it... they can't say it so directly.

Because I was shocked by the comparison, and it made me think that maybe there would be a more significant retaliation for the Kerch bridge than I has previously thought.
Personally I don't think they would do it, and I would see it as a massive escalation not a fair retaliation... but just having those two compared makes me think the Kerch is more important than I thought.
