I have no special insight into the alleged or assumed Great National Security Council Leak, BUT: if such it be, then the gloves are really coming off.
As citizens we all sleep more soundly when our politicians routinely stick to certain conventions concerning the really heavy stuff, however staid and boring and limiting that may be. When Michael Heseltine brandishing the Mace counts as outrageous conduct.
If we are moving towards times when that's no longer the case, well, a very different sort of politician can thrive where the 'conventional' ones are left floundering. Politicians with capacity for the same kind of untrammelled initiative as an imaginative military commander on a long leash, a pirate, or a mafia don. What they call in Russia absolut banditi. I mentioned Lenin the other day ...
A bracing prospect? Oh yes. Brace yerselves.
