Tariffs on Australia, Why

Donald Trump doesn't really understand international trade. He's a basic businessman who only understands strong arm tactics. He is also wholly unrealistic. He was quoted as complaining that Europe doesn't buy enough American cars despite the US importing ours. Well yeah, for one thing we have BMW, Audi, Mercedes, some of the best cars available. But also and somewhat more importantly, I'm not seeing many small cars coming out of America and our roads are not American roads. An 8 litre pickup truck is not much use here. Good luck driving that through European cities.
