The world feels pretty dangerous.

We have recently uncovered a staggeringly reckless campaign of Russian sabotage in Europe.

Danger is moving towards us at full speed.

We should expect to see continued acts of aggression here at home.

So what would happen if Britain's defences were put to the test?

I asked an Oxford academic for help.

If we could simulate some kind of threat unfolding, we could create a war game where we could

test ourselves and bring that to the public.

We chose a team to play the British government.

We put people who've had experience of doing this for real, back in the hot seat.

General Sir Richard Barons, I commanded Joint Forces Command, 2013 to 2016.

Mark Sedrell, a national security advisor in 2017-20.

Helena Kennedy, I'm a practitioner barrister.

And some of our former politicians.

Amber Rudd.

Jack Straw. James C.P.

I'm Ben Wallace, former Secretary of Safe Defense.

And I'm going to be playing the Prime Minister of the United Kingdom.

So we chose a bunker. We've created some maps.

We've got a Russia team. We had to go and ask them, what would Russia do?

When this red team gets together, and we have done this before, we run rings around the opposition.

Sometimes in ways that the UK doesn't imagine before the game actually starts.
