I donāt get why people keep saying Superman was a political movie, the only things really political about it were
Superman intervening in a conflict in the Middle East in order to save civilian lives
A twelve-minute long sequence where Lois and Clark debate the political and moral implications of Superman intervening in said conflict,
during which they note that the invading nation of Boravia is a close US ally despite their presidentās shady track record,
and that the invaded nation of Jarhanpur having a controversial government does not justify the mass slaughter of their civilian population (who also seem to be primarily Muslim)
Lex Luthor is a billionaire misogynist with eugenicist overtones who invests heavily into propaganda and misinformation to make himself look good and turn public opinion against his enemies
Luthor is also privately allied with the Boravian government and is providing them weaponry in exchange for half of Jarhanpurās land to develop in his own image
Luthor is operating a black site for-profit prison where he incarcerates political prisoners, whistleblowers and any ex-girlfriends that try to leave him
Luthor thoughtlessly murders an innocent Palestinian-American man just to taunt Superman, much to the cackling delight of Boraviaās pasty white president
Speaking of the Boravian president, when that guy orders a second invasion of the (mostly-unarmed) Jarhanpur, he publicly claims itās to āliberateā the people of Jarhanpur while simultaneously commanding his army to genocide the entire population of the country
and as an added kicker, the Boravian president at one point claims during a press conference that Superman is only saving people to build a āharemā of exploited women, before leaving to privately surround himself with fawning young women, and later visiting Luthorās private prison thatās full of kidnapped and abused women
The US government makes a big show of brutalizing Superman during his arrest before very publicly perp-walking him away (despite Superman actually turning himself over to federal custody, and also Superman apparently only being handcuffed with standard-issue cuffs due to the Earthās explicit lack of kryptonite)
When Superman points out that nobody read him his Miranda rights, Rick Flagg says āyouāre an alien, you donāt have rightsā before shipping him off to the aforementioned black-site prison
but other than that, I donāt think it has anything to do with politics at all
