As it turns out, snubs like this one are becoming increasingly common as Merkel appears to have lost control over her government. Two weeks ago, Defense Minister Annegret Kamp-Karrenbauer proposed a peace plan for Northern Syria without clearing it with the chancellor. Though at least during that incident, Merkel was given a heads up about the plan. AKK's ideas were pilloried by the Social Democrats and Foreign Minister Heiko Maas, and the whole incident ended up embarrassing the government as it seeks to combat speculation that it's asleep at the wheel.
Both Scholz and AKK are potential contenders to succeed Merkel, but with the resurgent Alternative for Germany party boasting solid gains in recent elections, it's difficult to imagine how things might go in 2021.
