After the sudden collapse of preliminary coalition talks among four of Germany’s political parties, the once hypothetical scenario of another grand coalition – not to mention a minority government, a hybrid “cooperation coalition,” or even a fresh election – is now very real. The Free Democratic Party (FDP) withdrew from the talks, dashing the hopes of building a so-called “Jamaica Coalition” among the remaining Christian Democratic Union (CDU) and its Bavarian sister party, the Christian Social Union (CSU), and the Greens. Although the talks stalled due to a “lack of trust” and irresolvable differences over climate and migration, the future of European defense policy will emerge as an important debate going forward. Should one of the political outcomes bring the CDU/CSU and the Social Democratic Party (SPD) to the formal negotiating table, here are three key defense issues to watch.
