That is why this development is so concerning. If Russia decided to be very irresponsible, which they likely will, and stop sharing scheduled tests and similar events, the west has an extremely short window of time to determine whether it's a legit threat or not.

NK doesn't announce theirs, obviously, but they aren't in a state of hybrid conflict with the west in the same manner as Russia is. Besides, their missle game is nowhere near the Russians.

To me it makes this more than posturing and saber rattling if they follow through with it. It is just one more signal we are regressing hard into the cold war, and it's not as cold as it once was.
