"What Must Be Said" (German: Was gesagt werden muss) is a 2012 prose poem by the German writer Günter Grass, recipient of the 1999 Nobel Prize in Literature. The poem discusses an alleged threat of annihilation of the Iranian people and the writer's fears that Germany's delivery to Israel of a sixth Dolphin-class submarine capable of carrying nuclear warheads might facilitate an eventual Israeli nuclear attack on Iran, and thus involve his country in a foreseeable crime.The poem was first published on 4 April 2012 by the Süddeutsche Zeitung, La Repubblica and El País, triggering four days later the declaration by Eli Yishai, the Israeli Minister for the Interior, that Grass, who had visited Israel in 1967 and 1971, was now persona non grata.
