(8.7.2017) The Hamburg Summit got off to a fast start on its first day with strong success on the key security issues of terrorism and nuclear proliferation. German chancellor Angela Merkel, as the host, wisely decided to open the summit with a leaders‘ only retreat where she focused on terrorism. This was the subject most likely to unify all members, including the otherwise difficult US president Donald Trump and Turkish president Recep Erdogan, especially following the recent terrorist attacks in the United Kingdom and the United States.
