The Defcon Warning System, a private organisation which monitors world events and estimates the nuclear threat against America, is now at Level 5 - its lowest possible state. Just weeks ago the warning was accelerated to Level 3 following increased tensions between US and Russia, with insiders fearing the West was creeping closer to nuclear war. Level 3 means US troops could be mobilised in as little as 15 minutes.

"Russia, however, will probably wait to see what the new President does, as well as now being hampered by the coming winter.” Donald Trump's election as president of America was welcomed by Vladimir Putin, leader of the US' biggest rival Russia.

The group did warn, however, about some remaining threats to US and world security. It said: “China and North Korea … continue to either cast a wary eye or are outright belligerent. Israel … will become more of a focal point again.

“Meanwhile, more troops are to be sent to Europe in 2017 to bolster defences against Russian movements and NATO continues building up forces in Poland and surrounding areas to protect against a potential Russian assault.”
