I doubt this latest thing is anything to worry about, just the usual Russian bluster and Trump replying in kind to them.
It’s really to counter the Russian nuclear strike threat, publicizing the movement is a signal to “us” not to Putin, he knows it happens all the time.
If the US puts Tariffs on Russian oil that will hurt Russia badly, China and India in particular. Because Putin is not negotiating seriously a deadline has been set by Trump, when that expires Im expect Ukraine will be allowed to attack more targets in Russia. The US may even supply more offensive weapons Putin will likely respond with a nuclear threat
