Russian military doctrine, published in 2014, introduced the new notion of “system of non-nuclear deterrence”, which supposes political and military measures to prevent aggression against the Russian Federation from non-nuclear forces. According to the document “Basic Principles of State Policy of the Russian Federation on Nuclear Deterrence”, which was signed by the President of the Russian Federation Vladimir Putin on June 2nd, 2020, high-precision non-nuclear and hypersonic weapons are among major military hazards. Since the beginning of 2020, the President of the Russian Federation Vladimir Putin stated more than once that Russian hypersonic weapons make missile defense systems useless. Following those documents and interviews, hypersonic weapons are becoming exactly the major factor of non-nuclear deterrence, at least for Russia. But, are hypersonic weapons capable of becoming the basis of non-nuclear deterrence?

Dear John,

My name is Alexei. I am 32. I am from Russia. I want to tell you a story. On a bright June day in 2014, I was in Cambridge, Massachusetts, having breakfast. The Charles River, the dark red-brick New England houses clad with creepers, the reflection of Trinity Church in the glass windows of the John Hancock Tower, the Prudential Tower from the top of which you can see planes taking off from Logan airport, and Harvard Bridge, across which it is a distance of “364 Smoots and one ear” to MIT - I really love Boston and its suburbs.
