US hegemony will continue to disintegrate, but the US military will continue to bomb and invade countries regardless. Much like the Roman empire, we will still be winning battles all the way up until our army collapses for economic reasons.

Iran will have a cultural revolution. Hard to say whether it will manifest as an explosion of art and music or a series of explosions and a civil war - I’m sure the CIA will push for the latter but the average Iranian will go for the former.

EU will go full fash, but unlike the fascists of the 20th century the brown wave will be too heavily tied up with neoliberal projects to do anything besides scapegoat minorities and virtue signal. Things will get worse for European Jews, Roma, Muslims, LGBT, etc but the only genocide that will be of non-Europeans at the border.

Red wave in southeast Asia, red wave in India, red wave in Africa and South America. The 2020s is the decade where all of the third worldists get proven right!
