British politicians have voted on an issue that will have a profound impact on the future of the country's security. They have overwhelmingly voted to renew the Trident nuclear weapons system. 

Britain's nuclear submarines are expected to be decommissioned some time after the year 2030. And for the past 10 years, there's been debate over what should replace them.

New Prime Minister Theresa May has said she wouldn't hesitate to launch a nuclear strike. And that Trident is a crucial pillar of Britain's security.

But is this kind of system still relevant? And can nuclear power really protect the world's superpowers?
