Translation of "étonner" in English

On ne peut pas s'en étonner. C'était à prévoir.

One shouldn't wonder about that as that was to be expected.

Rien ne saurait étonner un Américain. On a souvent répété que le mot "impossible" n’était pas français; on s’est évidemment trompé de dictionnaire. En Amérique, tout est facile, tout est simple, et quant aux difficultés mécaniques, elles sont mortes avant d’être nées.

Nothing can take a US American by surprise. It has often been said that the word "impossible" was not a French one. People have obviously looked in the wrong dictionary. In the United States, all is easy, all is simple and mechanical difficulties are overcome before they arise.
