US president’s threat comes after Germany’s Friedrich Merz suggests Trump team is being outplayed in its negotiations with Iran

In a post on his Truth Social platform, the US president said his administration was “studying and reviewing the possible reduction of troops in Germany, with a determination to be made over the next short period of time”.
