German Chancellor Angela Merkel’s government awarded itself a good performance report Wednesday, halfway through its term, but it was unclear whether that will be enough to hold the fractious coalition together for another two years. Merkel’s center-right Union bloc and the center-left Social Democrats agreed last year to assess their halftime performance, a novelty that emerged from tortuous talks to form what has become an often bad-tempered coalition of necessity. Merkel and Vice Chancellor Olaf Scholz both talked up the government’s performance at a brief appearance in Berlin.
