“When Iran gets into the news, especially with anything to do with war,” says religious historian Diana Butler Bass, “it’s a prophetic dog whistle to evangelicals.”
Last year a lot of those crazies proclaimed via social media, that the rapture was imminent and prepared themselves by undressing, writing last messages to the sinners who'll be left behind or they even sold their homes. Can't remember but it could actually have been when the 12 days war with Iran happened.
This rapture thing already should've happened a few times, just like with every end times prophecy. The fact the orange menace is in bed with the ultraorthodox christian movements (Dominionists, Seven Mountain Mandate) is well know since his first presidency. Same with their believes about the end-times. That he seems more like the anti christ is no problem for them as they believe, as stated in the article, that god will choose a flawed vessel for the mission.
AFAIK Russia doesn't need them anymore from Iran as they got multiple production facilities for Shaheds themselves and upgraded them in the meantime. And even if they were selling them to Putler, that is definitely not happening right now.
