Also about USA living at the expense of the rest of the world, printing their currency willy-nilly without the risk of devaluing it because all the main goods are priced in usd.

See how dollar plunges and US deficit becomes painful when usd is detangled from oil.

Then we will finally know if one can eat aircraft carriers and holywood movies.

Well you are soverign, and thus free to trade with Iran over the USA. It is really up to Europeans to decide if leaving their closest historical ally and trading partner is a good thing, just ao they can grow closer to Iran.

I would be really disappointed if it goes that way though.

It would appear that one man was allowed to turn an alliance into a hostage situation. So I guess all bets are off. And again, this is not about getting close to Iran. It's about not having your "ally" try to dictate all critical aspects of your existence.

You wouldn't want your friends overriding you on what to eat, what you drink, where you sleep, and who you talk to, would you? You'd question the nature and value of that friendship.

I wouldn't think that is a likely possibility given the impact tariffs would bring to all of us. What is more likely (and lets keep in mind we are discussing public policy of economical super powers) is that we would reach an agreement that the unilateral blockades and sanctions are really unilateral.
