Right, so basically bully other surrounding countries into stopping things getting into the UK? You assume France and Germany are going to be gungho about blocking off their neighbour because the US is pissed off at them for not renaming a body of water that isn't even theirs.
I think you need to understand something:
Tarrifs don't work the way Donald Trump says they will. The Exporter doesn't pay the tarrif, the consumer ultimately does, rising the price of imported goods. Trump also has the economic knowhow of a plank of wood because he also says he's basically going to have tarrifs on everyone as a way to make other countries pay America money (in his head). Again, that's wrong, and I don't think he's going to lift that on any EU country because in his eyes, other countries should pay America money either as a punishment or to pay for all the things the US does.
We can get our oil from the Middle East or Canada if needs be. The US is not the only place with Oil.
The biggest threat to France and Germany, or even Europe in general right now isn't China, it's Russia, because don't forget there's a War in Ukraine right now and Putin could, if he wanted to, send a force into Estonia or Finland and we could have nukes flying. We have Russian spies everywhere, Russian cyberattacks on infrastructure, fuck it wasn't too long ago we had poisonings of Russian dissidents in England.
Donald Trumps ideology on the international is basically "The Rest of the World Owes us, and we will make them pay", and I don't think Germany and France are going to suck America's cock over Britain, especially since Trump is quite pally with Europe's current big threat (Russia) and a certain member of his government is openly providing support for Far right parties in the UK, France and Germany.
What I think would happen is that Trump slaps Tariffs on the UK and EU, tells them to bend the knee lest he raises them, and the UK, France, and Germany basically look at each other and say "aight, bet" and raise tarriffs on American made goods. I don't think Germany and France are going to abandon the UK for a man who gets his money from Russia.
Anyone with the capacity to google knows that Trump's "Tariff-a-paloosa" scheme is going to blow up in America's face as things get more expensive because, again: Importers pay the tariff, not the exporter. And if there's one thing I know: You cannot make actual Scotch Whiskey, French Wine, or German Cars in the US.
Also, another thing you can't grow in a large scale in the US is Coffee! Only Hawa'ii can grow it and they can't grow it on a scale that can satisfy the market in the Lower 48 and Alaska, so I guess watching the coffee supply to one of the most caffeinated countries in the world get cut off will be interesting to watch.
Trade with the EU is still possible, it's just much harder to do. Unless the PM is Truss levels of thick, he would make a deal with the EU.
If the US tries to blockade the UK, that would be Article 5 worthy, hence, War with two nuclear powers.
Even if we ignore that: Attacking shipping between the UK and the outside world would also include attacking friendly or neutral countries, including EU and NATO members, because the channel is one of the busiest shipping lanes in the world. Hence, bad idea for America.
The Channel Tunnel (the Chunnel) allows for freight trains to pass between the UK and mainland Europe.
In short: If the US tries to blockade supplies between the UK and the rest of the world, be it by Sea or Air or Rail, the US would still be at war with NATO and the EU, as well as many other countries (the countries of the ships that are attacked for example) because the UK doesn't merely have a lot of allies, but they also get a lot of shit from the same routes the UK does.
So there's a lot of things about these drones being Aliens (and a lot of things about Aliens in general).
If they really are aliens, do you think beings who travelled here through interstellar space and the technology to come to earth within (we assume) a single lifetime are going to be felled by a fucking gun?
I don't think the Aliens are hostile because if they were, we'd be dead by now.
