on trump’s new banking sanctions against iran

According to the AP: today, the Trump administration imposed new sanctions as a result of which virtually all of Iran’s financial sector has been blacklisted.

In my opinion, these new sanctions are:

1. a last ditch effort by Trump to force #Iran to negotiate before US elections. Trump wants to tell voters his Iran pressure policy worked.

2- Iran banks are already blacklisted by the FATF (Financial Action Task Force). This is because Iran failed to ratify anti-money laundering conventions. Therefore, I am not sure how much more damage Trump’s new banking sanctions can cause.
