Wasn't the Saudi intervention before the Iran one?

Furthermore, the comparison is a bit off because Soviet military build-up on Cuba was merely a response to the actual nukes the US had in Turkey, literally on the Soviet border, but the US lost their shit in a typically hypocritical manner. Iran is purely projecting power wherever it can to combat Saudi and US influence in the region, it isn't a tit for tat response.
