That means to disintegrate.

Klingbeil: Transatlantic relations are currently disintegrating – Federal Finance Minister and Vice Chancellor Klingbeil has described relations with the US as severely damaged.

At an event held by the German Institute for Economic Research, the SPD leader said that transatlantic relations as we know them are currently disintegrating. Klingbeil referred to the US military intervention against Venezuela, the conflict over Greenland, and the US government’s new national security strategy. The Trump administration is making it clear that it wants to dominate the Western Hemisphere and is increasingly turning away from Europe politically and culturally, Klingbeil said.
