Nixon: “So we’re safe again.”
Doctor: “Safe? No, of course you’re not safe. There’s a billion other things out there just waiting to burn your whole world. But if you want to pretend you’re safe, just so you can sleep at night, okay, you’re safe. But you’re not really.
Thus the huge implications of 8 missing minutes from the records when the Watergate scandal broke.
And the Doctor was the one who told him to record everything!!
I love Doctor Who so much it hurts sometimes.
