No, I think it has to do with Syria, from the looks of things. Last time I checked, Iran is not the same country as Syria, but I could be wrong. In any case, the major "opponent" of the US in the Syrian Civil War is Russia, but we are clearly not going to go to war with them over this one country.
They have a mutual defense treaty. The US has been unsuccessful at provoking Iran, so they are trying to start a proxy war through Syria.

Assoudi's comments were first carried by the government-linked news agency Young Journalists' Club but were later apparently taken down from the group's website.
Iran and Syria signed a mutual defense pact in 2006, but little is known of its details, or whether there are any other signatories.
Sounds like a bunch of hot air coming from Iran. This "mutual defense pact" obviously hasn't seen much use, as Hamas has been attacking Assad yet it still receives Iranian funding. In any case, I doubt that Iran would be so foolish as to attack the US troops if Syria was invaded. They wouldn't stand a chance, and it would give Israel an excuse to crack down on neighboring Arab countries.
However, as far as I know the US government has no intentions to send actual troops in, so I don't see how Iran could be provoked into a war. I also don't see the point in going to war with Iran anyways, since whichever politicians advocated it would be committing political suicide.
