"it was Russia and not the EU that forced Ukraine into such a choice," Schockenhoff told Reuters ahead of a speech he is due to give on Wednesday in which he will criticize elements of Germany's stance."
Basically, he's telling the Socialist - SPD - too soft of a stand. Schockenhoff also criticizes Socialist Steinmeier's promise that Ukraine could never enter NATO.
...and yet Frau Merkel stresses how closely she's working with her new foreign minister, so criticism of him is effectively criticism of her also.
