DJ, If the EU was one country-not 27-the EU would be seen as the biggest exporter to the US. China would be the #2...

The US outsourced most of its production to low income countries in Africa/Asia/Latin America. Now "tariffs have to return those jobs to the US"????

A 104% tariff on China  reminds some of the tariffs on Japan prior to december 1941...

The US is buying most imports on credit...so US debts keep growing-as long as the US$ is a global reserve currency...

Iran moving away from fossil fuel to-among other-nuclear energy has been an excuse to claim Iran wants to build nuclear weapons. In the western view it is okay USrael has nuclear weapons...Claims the Saudi king had a "right of usage" of Pakistan nuclear weapons also was not a problem as long as both KSA Kingdom of Saudi Arabia and Pakistan were "pro-west"...

The Iran Islamic leadership claims for ethical/religious reasons it does not want nuclear weapons...(DJ-A point of view I share-NO country should want weapons of mass destruction !) 

Since 2022 Russian export via the Caspian Sea/Iran to India/Asia "exploded". Iran became a member of both BRICS and the SCO. It became an alternative for China-Europe/Africa trade via the Türkiye-Iran-Pakistan "landbridge" to/with China...So the EU could trade without using Russia. 

The US($) dominance is over...The US is no longer in control over global (energy) trade or even global finance...

A US attack on Iran has to restore US dominance...and brings the US even further in conflict also with Europe. The US blowing up Nordstream Russia-Germany energy link is part of a US-EU conflict. (The Euro/€ as an alternative for the US$ may also be part of that conflict...A "Euro-Dollar" (digital) currency never grew...).

So...the upcoming talks on a new Iran-deal will most likely NOT be maybe even on Iran...

It may be on rebalancing the globe...
