Could someone explain the sentences below? ''Foreign country' looked a little bit strange to me here.
The political talk at the restaurant was a foreign country to him. Ed had no use for foreign countries; that we were getting out of Vietnam was good enough for him. He’d been in the navy, in the Pacific.
Thanks in advance.
The term 'foreign country' here has been used as a metaphor for Ed's circumstances as he is unaware of the political awareness of the country being referred to in the conversation.
'Foreign country' may also denote an unknown arena which he is not bothered about as he belongs to the navy, i.e. serving his country.
Hope this clarifies a little?
