It's just domestic propaganda, Iran wouldn't ever dare confront Arabs directly. It will only arm proxies. A lot of Iran's policy consists of sectarianism. Because it's much easier to spread their influence by doing everything in name of religion. So Iran is actively trying to change demographics of Arab nations. It exagerates Shia's numbers but also Shias and Iran begin changing school cirriculum, begin changing mosques, start putting Shia banners all over the place and also try to force their views unto Sunni's. How they do this? Well some examples, they will start speaking in name of all Muslims. So lets say the situation in Syria, they will say all Muslims are united against 'Takfiris, wahabis'.
ANother example is they advertise themselves as victorers of 'Ahal ALbayt' meaning Household of Prophet, they try making it exclusive to them to force their view on everyone that they're true Muslims. But the reason they say 'AHal Albayt' is to portray Sunni's as enemies of the Prophet's family and as non Muslims and this goes back far. SO when we sunnis want to discredit their narratives through religious debates they immeditely cry victim and accuse us of sectaranism.
Shia's are like Persian missionaries who are trying to convert everone to their religion but only in the Middle East. Especially in Arab nations, that's because Persian empire used to consist of what is today Arab land. SO they use Shiasm as a tool in order to restore their influence. In reality Iranians don't believe in Islam at all, they think Islam is Arab and backwards, they just use their distorted Persanized version as a tool to gain influence in region. Iranians don't believe in their rhetoric, this is why you'll never see Iranians fighting in the wars in the region and are terrified of direct war. Because they don't want to sacrifice their lives as they live secular lifestyle. The religious rhetoric in Iran is intended for non-Iranan Shias so they can do their fighting.
You can read Shia forums, they make all kinds of excuses regarding opposing direct intervention from Iran anywhere in region. They even refer to it as a 'grand strategy', and this is begining to upset non-Iranian Shias because they're starting to realize Iranians are using them and that the whole 'divine revolution' is all a scam. This is why it's in interest of Arabs to get in direct war with Iran, because the Shia's elsewhere won't act up.

@WebMaster @Gasoline understand what I'm saying very well, it's hard explaining in english and may not make sense to Westerners but Arabs understand it.
