Reintroduce the possible authorization of the "Gay Bomb." Act like we are secretly developing it again, with it "accidentally" leaking to the Iranians. The Iranians will freak, thinking their military could actually "become gay" by a bomb (hoping for some language barrier confusion between English and Persian). If they don't call our bluff, we can have secret diplomatic leverage over the Iranians, for they'll be in fear of chaos within their military as we all know their pretty sickly stance on the LGBTQ community. The Ayatollah won't be executing gay Iranian citizens one day and letting is slide between generals another day. We're back to nuclear disarmament talks and a more peaceful stance between the US and Iran ensues. If the Iranians do call our bluff, we actually develop and drop a "gay bomb" onto one of their bases in Iran, away from civilians. The messed up Iranian command will probably arrest/imprison/execute military members affected, which can be used as evidence for human rights violations in the UN. The US develops significant support from the international community against Tehran's stance on LGBTQ human rights, leads a coalition effort into Iran, arrests top Iranian Officials for human rights violations, and establishes new elected officials into office. Coalition Forces occupy Iranian bases temporarily, most of the world sees this as a win, and then who knows what plays out.
Note: This post got a bit reddit-y, my apologies. I just wanted to be a bit creative in my story and in no way meant to offend anyone or any group of people. I am not against the LGBTQ community, and certainly don't know enough foreign policy of the Middle East and Iran to accurately spell out how something like my scenario would play out. It's obviously wrong for the Iranians to be executing gay citizens, but I hope my post gave you all a small chuckle on how to deal with the current Iranian government if I had some influence like the CSA may have. Cheers and good luck with your scholarships everyone!
