Eleonora Harwich: What must be done to bolster our cyber security – and save lives

The next National Cyber Security Strategy is due next year, and must have a strong focus on addressing this skills gap.

Julian Brazier: The future of the Army – and why Haldane’s approach remains the best.

His instinct to bring together various reserves to create a ‘Second Line’ was crucial in the First World War; leaders today should take inspiration.

Russians in the bed?

If Putin hoped that Brexit would detach us from our alliances, there’s no evidence of that happening so far, and much to the contrary.

James Wild: The security, defence and foreign policy review is underway. We cannot afford to duck, delay or defer the big decisions.

In the private sector, constantly over-spending your allocated budget would not be dealt with by a bailout but by being shown the door.

Hugo de Burgh: We owe it to future generations of Brits to work with China

It is our third largest market – we must work with it if we are to help resolve global problems from the environment to nuclear proliferation.

Richard Bingley: A cyber war is on the way

Iran, accustomed to artful brinksmanship and operational deniability, and equipped with an experienced cyber army, may take its revenge online.

This year’s Security, Defence and Foreign Policy review provides an excellent opportunity to reinforce Britain’s place as a leader in this field.

It is rare to hear the defence establishment talking plainly about the need to protect Britain against external threats.

Ruth Davis: Cyber threats are the new norm – and not just from Russia. Business needs to up its game.

Government research shows that the average person is roughly eleven times more likely to be the victim of cyber-crime than an in-person robbery.

Syria. May’s calculation and the dangers of a May miscalculation – to others and to her

She will be feeling a hand of history on her shoulder, and wondering if the other holds a knife at her back.

Bob Seely: Post-Brexit, we need to be the world’s smart power nation. Let’s make it happen.

Our plan seems to have been little more than to cobble together just enough kit to make us a Great Power on the cheap. That cannot continue.

Bruce Newsome: The Government must get real about counter-terrorism strategy

No more foreign funding of extremism. No more self-appointed “community” intermediaries. No more pretence that it’s all about cyberspace.

There should be no room for Putin apologism on the right

The fantasy that the Kremlin is more sinned against than sinning was once the preserve of Corbyn’s hard left. We should stop the rot.
