Yeah that's mental. Why would you want to enter into a trade war with the EU for no reason? Again, they'll just choose to purchase more from countries in other parts of the world that don't engage in putting trade sanctions on their closest trading partners for no reason.
You misunderstand that the EU wouldn't be choosing to do anything.. tariffs would be applied by default. And then your answer would be to further cripple our economy by raising tariffs on the EU when we rely on imports to produce stuff in order to export? We literally need to import raw materials . Getting into a trade war would just mean they buy less from us, and our 50% of our economy would end up being subject to increased costs. In fact 100% of our economy would be affected because we'd also not be able to trade with the rest of the world under the terms negotiated through the EU.
That's a possibility DB, there could be other debts lurking also, we need Bear72 to come back with the information and amount owed before any further advice can be given, especially as we need to know exactly what capacity B & S are calling as. EA for Ctax or HCEO.
