In this case, the sarcasm is intended to confuse, and with some readers it achieves a little more confusion than intended.
kamma could have written something like "the EU should solve <really difficult problems> before concerning itself with <simpler problenm>" but that would have made clear that the really difficult problems are really difficult. The sarcasm is rhetorical device to distract the readers so they won't pay attention to the different levels of difficulty. Handwaving, basically, and the handwaving was a little too strong and distracted some readers too much.
If you've been long enough on internet forums, you'll see every inanity you can think of as "of course it's sarcasm" being presented sincerely.
Also, I've read too many posts/comments of the "the world has never been better" variety (usually citing Hans Rosling or some tech-bro favorite like Pinker), that sincerely push similar ideas of the state of the world in 2024.
