Would we be ready if Russia attacked us tomorrow?
"No" is the simple, sobering answer from series writer and presenter Deborah Haynes.
"It's stated in the defence review, it literally says in black and white that we are not ready for war at the moment," she says.
It's not scaremongering, she says, to answer the question of the UK's military readiness.
Haynes speaks of the decline in military spending and capability since the fall of the Soviet Union.
"And so the armed forces that we have today, as a result of the past 30, 40 years of evolution and change and what is being argued now by those inside defence, and outside too, who have a grasp of history, is that reality has changed, the threat has changed, and therefore the armed forces need to reconfigure to confront that threat," she says.
