I wish for the Power of Friendship to become tangible and be weaponized in the military
Granted. Sadly, the US military is corrupt rendering the power of friendship negligible because the soldiers aren't united within nor are they united against their enemy factions, they just want to get their pay by shooting some middle eastern people and leave. Same goes for the Russian and Ukrainian armies.
However, the power of the brotherhood quickly becomes prominent for the North Korean army and they would take South Korea by force. The force becomes greater as an active oppression of sources of information tends to unite the soldiers as they have less distractions in the military. Eventually, the US would be forcefully taken by authoritarian regimes such as North Korea via a landing in California in the long term, that is forseeable.
More than that, gangs and drug rings could actually attack or manipulate people to join them or to die solely because bonding is prominent as well in those leadership groups. the US is quickly ridden by these underground criminals and the ass in the pain is collectively shared as a problem for all countries in the world.
Geniuses are being repressed because the power of friendship of three people each less than 1/3 of his collective abilities are able to get a massive boost due to their "friendship". Scientific progress halts because... well, those who win are almost guaranteed to not be lonely geniuses or at that level except for fields where no one cares about, like geology. Nepotism springs upward as well as their interpersonal bond with the wealthy and the powerful and the related can manifest tangibly instead of figuratively. Opportunities are given towards those who wouldn't deserve it fully and rightfully, and in all fields a tyranny of the many would quickly become the status quo as those who side with the initiator on anything could possibly win just by the bond, even if the initiator calls batshit crazy stuff such as increasing the educational spending & funding up to $500B.
