Iran’s Foreign Minister Abbas Araghchi tells Al Jazeera that launching a military attack on Iranian nuclear sites would be “one of the biggest historical mistakes the US could make.”
Araghchi says Tehran will respond “immediately and decisively” if its nuclear sites are attacked, which will lead to “all-out war in the region.”
Remember, Iran warned that it will mount a massive attack on Israel since the end of October.
So where's World War III?
About 90% of Iranian air defense systems are warnings of huge consequences for attacking. When you understand that these regular threats are meant to dissuade - which is a lot cheaper than a decent air defense system - you can understand why Iran says this stuff regularly.
Just like they claim that Israel's dismantling of Hezbollah, Hamas and Syria's fall didn't hurt it at all.
One day, reporters will be able to tell the difference between frightened bluster and real threats.
Not that Iran would do nothing. They could attack US facilities in Arab countries; they could enhance the Hothi style blocking of US ships in the area, they can generally make themselves a nuisance. But Iran wants war a lot less than the US does, because they know that a war means the end of the mullah's regime.
Which is as strong a reason to attack as targeting Iran's nuclear weapons program.
