I do think Iran not responding right away but forcing the US to spend more billions they don't have, supplying Israel and moving a ton of military equipment to the Middle East might be the right move.
Iran knows they will win the long game. Time is not on the side of the USA. They just have to keep their young people happy, and a war will crush this goal. Keep feeding their proxy armies to keep causing trouble and keep letting the USA destroy itself with Marxism.
If I was Iran, I would implement the following...
#1) Nothing is more important than getting a nuclear weapon. They should be sparring no expense in doing this.
#2) I doubt their vote means very much, with the religious leaders controlling much of everything, but I would change their voting to Men only, over 30, and only men with children. Send a strong message that we value your input, but only once you have earned it through both age/experience, having a vested future in the country, and that men have the responsibility to fight for the country, so they get the opportunity to vote for their leaders.
