Even Iranian opposition could be involved in this. Russia is not particularly popular outside the mullah cult.
That's a thing.
Russia hit two Turkish ships in the Black Sea and Erdogan went begging to Putin to have a ceasefire in hitting commercial shipping. Putin declined.
More stuff is going through the Caspian Sea as a result of the Black Sea being too unpredictable and dangerous.
Ships carrying arms from Iran to Russia have now been hit in the Caspian Sea ha ha (see post above). Iran is an ally of Russia.
The pattern of Ukrainian drone strikes is emerging. This on top of a massive multiplication of drone production. One (probably over optimistic commentator) predicted 3000 drones per day into Russia - more like 1000 but if it has military or commercial value, it's a target. Ukraine is exceeding Russian drone production. Russian drones have a success rate of about 8 to 10% only. The Ukrainians are much more effective with the same oil refineries being hit repeatedly and military targets taken out with little resistance within the backdrop of very weak air defences. Putin has withdrawn countless air defence systems from other areas to protect Moscow.
