Bluster- Aggressive way with little effect

President Trump's speech was a curious amalgam of threats, bluster - a touch of de-escalation.

Nonetheless he still slapped on more economic sanctions against Tehran. He triumphed in the killing of Gen Soleimani, whom he described as "the world's top terrorist".

But there were essentially three key messages. First, de-escalation. There were no US casualties caused by the Iranian missile strikes. He said that Iran was "standing down", presumably returning its deployed missile forces to their bases. He did not threaten an immediate US response.

Secondly - the nuclear deal. He called upon the other signatories to the 2015 nuclear agreement - the JCPOA - which the US long ago abandoned, to similarly give it up as a bad job.

Thirdly, stressing US energy independence, he called upon Nato countries "to become much more involved in the Middle East process". This will inevitably be seen as another signal that the US is tiring of its role in the region and THAT will not be welcomed by his allies either in the Middle East or in Nato.

So this was a speech full of Trumpian contradiction and the few references to a brighter future for the Iranian people provided little tangible hope of any new diplomatic initiative. So in the wake of the US drone attack and Iran's missile strikes it appears to be back to business as usual.
