It’s so crazy I don’t have the time to explain it all. It’s also so by the numbers it’s absolutely mind-blowing. The synchronization has been happening for years- basically from the start. Their solo projects and group projects over the years have contained elements. Even BTS’ connection to the Barbie movie relates to this, as that Barbie movie very much relates to the current season we are in. It would take a book, maybe two, to try to cover these things. If only I had the time, lol.
South Korea is a US ally. And remember BTS went to the US and spoke at the White House and met both Biden and Kamala in 2022. And if you do recall (or care to look up) there were articles back on inauguration day 2021 about Kamala being ARMY, wearing purple for ARMY, and following BTS on her official VP twitter account at inauguration.
Also worth noting is that BTS are in with UNICEF and the UN. And as you pointed out, BTS is very “youth-oriented”. They made it a point to reiterate their youth-orientation this spring and summer with the “enternal youth” Monochrome pop- up thing. Kamala is youth-oriented as well. Both BTS and Kamala Harris have Asian heritage as too.
