Germany's coalition government called, and then hastily canceled, a press conference on Tuesday evening to present what it hoped was a breakthrough on stalled plans to reintroduce military service.  The CDU has resisted a proposal put forward in August by the defense minister, envisioning purely voluntary recruitment, saying it was concerned too few would volunteer.  Its proposed solution was a lottery among young men who did not volunteer, if it is needed to bolster the ranks in a given year.
