If not you, who?

In Germany they first came for the Communists,
and I didn’t speak up because I wasn’t a Communist.

Then they came for the Jews,
and I didn’t speak up because I wasn’t a Jew.

Then they came for the trade unionists,
and I didn’t speak up because I wasn’t a trade unionist.

Then they came for the Catholics,
and I didn’t speak up because I was a Protestant.

Then they came for me –
and by that time no one was left to speak up.
