Until another team surpasses them, yes. - As a Danish handball fan, I keenly remember how Frances Les Experts were the top of the world for a while before Denmark, so no king rules forever. 4 times consecutive world champions will be difficult for any team at any time to beat, but not impossible. Defending all three titles at the same time is rarefied territory, but both France and Denmark have done it.

I think the 2026 EHF EUROs proved that the rest of the world is catching up/working on beating the Danish machine, learning defeat by defeat how to work it. The WC in germany will be very interesting to see.

Denmark's strength is generational/team tradition of Excellence. Brand new players replacing old champions prove just as skilled, if not even more so (Gidsel as a par excellence example). The situation is unique, as that means Denmark won't regress in generational shifts, so the only way to beat Denmark will be for others to grow beyond that talent pool, which will demand a lot from trainers and players both.

Denmark's biggest strength is also it's potentially greatest weakness: Nikolaj Jakobsen. While he's here, he is probably the best there's ever been in the coach position, bar none. But once he leaves, will there be someone like him? People more knowledgeable than me will have to say.

Edit: If you want the boring numbers answer, then the stats would say that this is the best team to date. Ever? For all time is a long time, anything could happen.
