Non-sequitur and false dichotomy. Regarding the 4.6x26mmR and 4.6x30mm as underpowered and meek from an infantry rifle perspective, is in no way the same as arguing for going back to battle rifles.
5.56x45mm (and 5.45x39mm) is literally THE perfect power balance for an infantry rifle, there is no other sensible option for the U.S Army but trashing the NGSW program and sticking with 5.56mm

Both the M4A1 and the AK74M have:
>very flat trajectories and good effective range
>close to no felt recoil at all, these are very easy weapons to shoot and control
>lightweight ammunition where you can easily carry 240rds or 300rds in aluminum or synthetic magazines
>very strong terminal ballistics, both 5.56mm and 5.45mm will make entrywounds the size of a fist at CQB ranges

Future improvements to me would in the immediate sense be to move over to even lighter weight polymer cased ammunition for these cartridges, and at some later future point a cased telescopic copy of the 5.56mm.

>Sweden was pushing ideas to ban American 5.56 round as inhuman because if it's fragmentation.
Unsurprising, but it sounds like the typical liberal demsoc virtue signalling noise, and which couldn't really amount to anything, because it was immediately at odds with reality on its face, and Sweden was essentially a secret NATO member during the Cold War, NATO wouldn't have allowed it.

>RAP rounds with sustaining motor like Kellgren suggested
Ok, I need to stop procrastinating and read this paper, I love fucking this madman.

5.56 is quite a nasty round to get hit with
