I have a question about the correct preposition to use with "isolationism" and "isolation". On the web, I found examples along the lines of:
- The country retreated into isolation.
- The country retreated into isolationism.
Isolation is the state of being alone. Isolationism is the idea or policy of a country not having relations with other countries.
The phrase "retreat into isolation" seems normal to me, because a country could be "in isolation", and so it could definitely "retreat into isolation." But, "retreat into isolationism" seems off to me, because a country could not be "in isolationism".
What do native speaker think? Is "retreat into isolationism" in sentence 2 wrong?
