[Official] US announces new tariffs on most countries

It's not a "media trick". Pretty much the entirely of economists, bankers, manufacturers, etc consider Trump's approach to be "insane", "idiotic", "grotesque", "oversimplified", etc.
The truth is that Trump really doesn't have a clue what he's doing, but the culture of sycophancy in the White House is now so advanced that literally no one in his inner circle will offer any contradictory advice.
The policy is already proving to be a disaster, and is unlikely to get any better.

Which of the UK tariffs and trade barriers in place against the US do you most object to, and why?

I think economic options not military options against the most powerful military machine on the planet.

That would be fair if done in practice. I doubt the EU would suddenly abandon their protectionist policies to engage with the rest of the world.

I don't object to any UK tariffs. I support the UK protecting British businesses and interests. I was commenting on the US approach.

Deffo, trump is on a madness with these tarrifs we will be next.

Already happened.

Which of the EU's protectionist policies do you most object to, and why?

But you said...
"Are you saying that there are no tariffs or trade barriers whatsoever in place against the US?"
So clearly you were commenting on tariffs and trade barriers against the US by the UK/EU. Those are not determined by the US.

President Trump explained the car tariff difference during his speech.

I think economic options not military options against the most powerful military machine on the planet.

I was acknowledging that there were tariffs.

Ironically, America's ragtag alliance took on arguably the most powerful military machine in the world, and won.

But you don't object to them?

Selling all our $ reserves?

Trump has difficulty explaining what day it is.
Any chance you could explain it, and why you object to it?

"A European manufacturer could have part of their manufacturing based in the US, which ships components for final assembly to Europe."
Unlikely. Labour and other costs would tend to make this prohibitive. Components are usually manufactured in countries with more commercially attractive systems.

That would be silly.

So not even all economic options then.
