I assure you that to put the missile to target requires a great deal of conscious operations a stranger won’t be able to do. That’s going to be the whole different sequence of actions to fire it towards Poland or at the missile incoming from another direction.
Okay, if you insist. But what about drunk? Lots drunken soldiers thereabouts. Again, could have been deliberate, with or without orders from higher up. I’m just not ready to call it either way.
That old Soviet junk is pretty unreliable, anyway. I remember back in the late 1990s, seeing for myself the sorry state of the Russian army (it was painfully pathetic at the time), all I could think was “And we used to be so scared of the Red Army?” Regarding their rockets and missiles, a Russian officer wryly remarked, “Mostly, they do not work.”
