BERLIN, July 9 (Reuters) - Germany will purchase Tomahawk cruise missiles from the United States and station them on German soil, Chancellor Friedrich Merz said on Thursday, in a shift from planned U.S. deployments to Germany's own long-range strike capability. Merz told lawmakers he had sealed the deal with the U.S. government on the sidelines of a NATO summit in Ankara, adding that the meetings on Tuesday and Wednesday had exceeded his expectations.
