But in a jibe against at Trump's America First policy and his insistence on building a wall on the southern border with Mexico, Steinmeier underlined the yearning for a return of the transatlantic partner of the past.
"This America as a mutually respectful partner, as a partner for democracy and freedom, against national egoism -- that is what I hope for in the future too," said Steinmeier, as he opened festivities at the spot where Reagan once stood.
Steinmeier's sharp words at the festivities underlined growing tensions between the traditional allies, after Germany was rattled by Trump's go-it-alone attitude on issues ranging from Iranian nuclear policy to trade with Europe to climate change.
