You didn't invent microwaves. Well, your lot invented the klystron. Know what a klystron is? No? Well there you are.

Cellular phones were invented in the UK and Finland. The US didn't even have them until the first couple of generations were obsolete here.

Transistors were invented in Germany, although they were made practical in the US, I'll them that.
