According to video analysts, the drones appeared to be the winged type (as opposed to the quad copter type). Winged ones have a much longer range, can stay in the air a lot longer, and are a good deal harder for amateurs to get hold of.
Not sure what to make of that. Could also be Russian partisans, using the war as a smokescreen.
There's not much reason for Ukraine to attempt to assassinate Putin. Call me cynical, but it seems much more likely for the war to outlive Putin than for Putin to outlive the war.
I'm not sure if there's any truth to the persistent, but only anecdotally supported, rumors that Putin is in very poor health, but reading between the lines it's clear that he's only the tip of the iceberg. A sort of bureaucratic figurehead of a fanatical nationalist and imperialist cult that is in control of government and military.
The fact that Russia is rushing into this war now, rather than, say, during the Trump administration where they could have counted on the American governments approval, or to a later point when their army would actually be prepared for a war of conquest suggests two possibilities.
Either Putin is a true believer in Dugin's dream of a Eurasian Empire and sees that war as a a desperate attempt to secure his legacy as some great warlord before he dies, or that he's gotten to weak, politically or physically, to maintain the balancing act between appeasing the ultranationalist right in his own country and maintaining relations with Europe and its allies.
He was hardly ever a dove but for a while he pretty successfully projected an impression of power internally, while mainly pushing Russia's influence through trade, subversive propaganda and support of an emerging far right movement in most western countries.
I can't speak for western media as a whole, but until he broke off the ongoing war, Putin was an absolute darling of German media. He was treated as some sort of machiavellian puppetmaster, as the man whose firm guidance liberated Russia from the lingering spectre of communism and restoring it to its place as one of the most powerful nations on the planet, excusing his crimes against his own people as the Russian people simply being "not ready" for real democracy, or human rights or social justice. I'd be a rich man if I had a Euro for every time I had to read the sentence "Putin schafft Fakten" during the Syrian War or the invasion of Crimea. Which makes it all the more funny that now that they can't defend him anymore, they started implying he was a communist all along.
Either way, the fact that he's rushing headlong into a war he has yet to present any meaningful successes in suggests that he's either losing control of himself or of his government. Both would make it very likely that the war could and would continue without him.
