City on alert for possible Iranian terrorist attack

What an ideal time for them to attack the US, with everything in discordant disarray. Trump could then declare martial law and refuse to leave office. Iran could score a big win.

Would they attack Argentina again? Why?

I guess the only reason they would attack Argentina is because it would be an easier target.

The main aim of these types of attacks is to spread fear amongst enemies. Sure, a major attack in Argentina would make headlines, but it would be forgotten about in the States and Europe days after.
