They took Kursk

What are you talking about, they made it less than a third of the way to Kursk

Forbes seems to disagree with you there bud https://www.forbes.com/sites/davidaxe/2024/08/17/out-in-the-open-and-on-the-move-in-russias-kursk-oblast-ukrainian-forces-are-vulnerable-and-losing-lots-of-armored-vehicles/

Also, not sure what you mean by "took Kurks", if you mean took a few villages by the border where they're losing way more troops than they did in dug in and prepared positions they were defending, then yeah big success.

Also, not sure how you think this is a bargaining chip. Given that they can't even hold well prepared positions in Donbas right now, how long do you think they'll be able to run around in Kursk?

Nor has this stunt diverted any Russian attention from the main front. https://www.ft.com/content/daa1a6ad-9ada-42ba-bfb2-2c199118e904

The reality is that Russia has far more troops than Ukraine at this point because this is primarily an artillery war with 80% of the casualties being artillery fire and where Russia enjoys roughly a 10x1 advantage in artillery. As a result, Ukraine is losing troops at a far faster rate than Russia is, hence why we're seeing a general collapse of the AFU unfolding.

Finally, pretty sure that western reporting is the last thing Putin cares about. This whole thing has been a gift to Russia because it weakened Ukrainian defenses on the main front, and put best Ukrainian troops in a vulnerable position. All Ukraine managed to accomplish is to speed up their own defeat.

The only thing it managed to do is to sabotage attempts at mediation and proposed partial ceasefire. Seems like factions in Kiev are started to tear itself apart, or their government branches does not coordinate to this point, or Uncle Sam's hand is still squezing them hard enough to force such obvious blunder (or all three in combination).
