i mean, i provided the timeline. bts' definitive solidification as a breakout artist in the u.s was with dna and subsequently micdrop remix, both of which were out in 2017. bp's western breaktrhough was with dudududu in 2018. i was here for all of that. if you search google im sure you wont see any article including both bts and bp and comparing their western success dated before 2018.
But are those articles written by YGE specifically? Because if not, that's not really good proof tbh
