The Russian president warned his citizens there were "dangers and risks in our day to day life" as he was quizzed about the prospect of all out war. Speaking at his annual news conference, Mr Putin said: "The danger of the situation escalating is being downplayed. It now seems to be impossible, something not of crucial importance. "But at the same time if something like this would happen, this might lead to the collapse of the entire civilisation, maybe our planet."
Mr Putin said it was hard to predict what the consequences would be of a US withdrawal from the landmark Intermediate-range Nuclear Forces Treaty, signed in 1987.
Speaking directly to his American counterpart, he said: "It expires in 2021, we do not have any negotiations in place as of yet.. you’re not interesed in that, you don’t want to keep that, that’s okay we can ensure our safety, we know how to do that."
He said Russia was not "striving to have an advantage" over the US in terms of nucelar capabilities but to ensure "safety".
But in a strong warning to Mr Trump, the Russian leader said he would do whatever was impossible to "ensure the safety" of his nation.
He told the audience the risks were "the collapse of the international system of arms control, of moving away from an arms race after the US withdrew from the relevant treaty, that was the cornerstone when it comes to non-proliferation and putting an end to an arms race.
"We had to respond with creating a new type of weapon to overcome this engine missile defence systems and now we hear Russia has an advantage when it comes to weaponry systems.
"Of course other countries don’t possess such systems but they are gong to develop such systems and this does provide us with a certain advantage. This is about about equal conditions, having parity when it comes to our weapon arsenals."
