Of all the ill-informed things you have said, this stands out. You must not have any idea about the size and readiness of the UKs military.

I mean, the UK has enough nuclear warheads to destroy Russia, so he isnt wrong. If it was a conventional war, well, the UK certainly couldn’t destroy Russia, but given Russia’s pitiful performance in Ukraine I dont see how Russia could project its conventional power directly at Britain when it couldn’t even achieve air superiority against a country with a handful of rusty soviet migs.
