Well, *that's* encouraging. (It really, really isn't.)

When dignitaries of an uninvolved country visit a war zone, standard practice is to give all combatant governments a heads-up so that they know not to attack the area where the foreign VIP is about to go. Yesterday, Ukrainian president Zelensky was showing Greek PM Mitsotakis around the port facilities in Odessa when a missile launched out of Crimea struck "less than 500m" from the delegation. If that was a genuine accident, it's a staggering failure of Russian military command & control. If it was intentional, then they're playing fast & loose with the escalation ladder. Neither is exactly reassuring.
