Putin was strutting his testosterone before the meeting in Vietnam. As usual, it is always brinkmanship. Putin isn't writing or receiving "beautiful letters" and he has to get attention some way.
To begin with, does anyone actually think Vladimir Putin is going to display the ONLY weapon he has to defeat a nuclear attack to the public? ONLY weapon? Give me a break.
If this is Putin's best hope, then he doesn't have one. There are a million holes in what he is saying about a nuclear confrontation with The West. The article about the Project 20380 is from 2017. This is not new.
Kim is a lot younger than Putin, so it is understanding why Putin is strutting his stuff.
The INF treaty was written by Ronald Reagan and Mikhail Gorbachev. The treaty has existed a while. Basically, it only deals with short and medium LAND BASED missiles.
500–1,000 kilometers (310–620 mi) (short medium-range)
1,000–5,500 km (620–3,420 mi) (intermediate-range)
The treaty does not apply to air or sea launched missiles.
So, the hypersonic missile was never covered under the INF. If this is what Trump is referring to in ending the INF treaty then he has no basis for his actions. Canceling the INF without due cause is a reason for Russia to be hopping mad.
USA effected missiles with the INF Treaty according to NATO.
BGM-109G Ground Launched Cruise Missile (decommissioned)
Pershing 1a (decommissioned)
Pershing II (decommissioned)
Soviet Union effect missiles with the INF Treaty
SS-4 Sandal (decommissioned)
SS-5 Skean (decommissioned)
SS-12 Scaleboard (decommissioned)
SS-20 Saber (decommissioned)
SS-23 Spider (decommissioned)
SSC-X-4 Slingshot (Mobile missile launcher)
It could be argued the INF Treaty was old and ineffective in modern day war, however, in dissolving the treaty it allows Russia to begin to build is' SOVIET missiles all over again. So, all in all, it was best to leave it alone.
It also could be said the INF Treaty was between the Soviet Union and the USA. The Soviet Union doesn't exist anymore.
To just regroup on all this, if Putin is stating he has some radical new missile that will turn the USA into a nuclear wasteland, that is overstating Russia's abilities. Somehow the Russian audience is supposed to come away with the idea that Russia's defense or offensive first strike weapons are radically new and the USA is somehow behind the eight ball. The USA has known about this missile for a long time. Yes, I consider AT LEAST two years a long time. Now, either the Russians deployed these missiles in response to the USA weapons deployed or they really have no other measure of national security and Putin figured, "Go ahead, why not?"
Vladimir Putin is a brinkman. He has practiced brinkmanship in the world for as long as he has been a leader for Russia. Ask any USA general retired or otherwise and they will tell the stories of how the Russians showed up with all kinds of bluster about their ability to begin a nuclear war. So, this speech is not a surprise, the only aspect of this which is NEW is the fact he is making it before Trump meets in Vietnam with North Korea. Like I said, either Putin is jealous beyond imagination of the affection between Kim and Trump or Trump is scared down to his skivvies of Putin. I do believe Trump has a yellow stripe down his back to put dandelions to shame.
