Writing from Estonia, Ukrainian drone attacks on the Russian ports of Ust-Luga and Primorsk (on the Gulf of Finland in the Baltic Sea), whereby they export at least 30% of their oil, but perhaps even 40% in recent times - have indeed been very intense during the past week.
Day after day, large swarms go and many hit their targets despite heavy-handed air defense. The smoke of burning oil is visible to 70 km distance and some confused “birds” end up landing here (one hit a concrete smokestack, another fell in an empty field). The traffic jam of cargo ships and oil / gas tankers on the Gulf of Finland is considerable, sailors describe it “like a new city appearing on water”.
If this is what it takes to force Putin to end his war, I have no complaints.
But we should be aware that due to Trump’s simultaneous adventure in the Persian Gulf, which was entirely avoidable, and has entirely predictable results, a global economic recession is currently a realistic outcome.
If I were in the shoes of Zelensky, I would advise Trump: “please, do save the global economy by ending your adventure in the Persian Gulf, we cannot have a pillow fight with Russia, they are extremely serious and not easily dissuaded (have been attacking 4 years)”.
Meanwhile, his statemement does offer a pathway to somewhere…
“If Russia is ready not to strike Ukraine’s energy, then we’ll respond by not attacking theirs.”
…it’s merely that Russia has shown willingness to cause a humanitarian crisis in Ukraine by destroying their energy infrastructure in the winter that passed, and Ukrainians now have very little reason to believe mere words that it won’t repeat next winter. There will have to be at least ink on paper to assure it won’t happen again.

Yes, I have seen video of an Ukrainian interceptor blow up a Shahed strike drone above a city where people speak Arabic (and I’ve seen an US fighter plane fail the same task).
Ukraine needs missile defense. Missile defense is hard to come by and slow to develop.
However, Ukraine has the most advanced antidrone defense in the world, thanks to endless practise… in part due to Iran supplying Russia with blueprints for Shahed-136 production about 3 years ago (Russia has since surpassed Iran in both volume and skill, again due to endless practise against Ukraine).
Thus, Ukraine tries to bargain with Arab countries to get whatevever remains of available Patriot PAC-3 supplies. In return, it offers cheap interceptors, advise about how to use and make them, how to jam navigation and communication, how to use PAC-3 more efficiently, etc.
I am not aware of any Ukrainian attack on Iran.
Overall, Iran should have absolutely no reason to complain about Ukrainian involvement, since they have supplied Russia. And besides, Ukrainian involvement is not limitless - so far Ukrainians have been helping defend third countries (which made the mistake of hosting US bases, but regardless have reasons to defend their airspace).
Yes, it’s a mess. I hope it ends, as there is no positive outcome from continuing. Currently the best way of ending it seems like the US ceasing its campaign (not happening, a third aircraft carrier is moving towards the Middle East) and Arab countries negotiating with Iran to open the Strait of Hormuz for traffic. But all of this involves the orange person admitting a big mistake. He is currently doubling down instead.
Ukraine has its own interests (get missile defense supplies from anywhere) and will pursue them anyway. Can’t buy from China or South Korea, supply from Japan is tiny, supply from Germany is of the wrong type or not yet started up, supply from France and Italy is very limited - they will find any missile defense anywhere and try to see if it can be bought (while rushing to make their own based on the Soviet S-300).
