This was only a cover-up by the Merkel administration to win the election in last autumn. Of course, some people that where in the delegation wanted to get some little success to bring home ... but the US showed that they are the rulers and the US is the big boss.
I hope, that slowly some people in Germany wake up. The success of Merkel shows, that many still dream their econony wonder (German: "Wirtschaftswunder") dream of the 70s. But the Germans do not realize, that they have been mucked around. Germans are the country in Europe that has sold their interests most to the US, maybe with the exception of Britain.
