How dependent is the economy of the world on the United States?
Can US policies have disastrous impacts on other superpowers in the world such as Germany?
For example, take into account countries such as Iran and Turkey which were hit by US sanctions and their economy soon deteriorated.
I want to know if the same can happen to a country like Germany, UK, or Japan if at some point in time US decides to impose similar measures on such countries or even decide to stop doing business with them?
In brief, can German economy, as an example, survive without the United States? Are they heavily-dependent on the US?
