There are two possible Flynn-Bannon-Trump strategies on Iran worth considering.

I. The first is that they're setting the table for war with Iran, plain and simple. The administration will use the recent missile test and subsequent Iranian noncompliance to create a pretext for starting a war. Look at what Flynn thinks about Iran's role in the Middle East, and it's clear that he feels Iran needs to be met directly by force for countering the US's designs for the broader region (see Iraq, Syria, Yemen, and the ailing peace process)
