Incorrect. Russia's violation of the INF Treaty is the next step in a global arms race. The US withdrawal from the treaty is a common sense response, since a treaty that one side is violating is worthless.
So the US doesn’t supply proof. Has a history of tearing treaties. Has been almost surely in violation of the INF for some time. Is poking holes in the last few remaining treaties.
But don’t worry about Armageddon: w/out an arms treaty, launching the thousands of obsolete ICBMs loaded with tungsten carbide bearings into orbit solves any countries’ security concerns vis a vis space ;)
