German Chancellor Friedrich Merz visited the White House on 3 March carrying two explicit messages. First: "Europe will not accept an agreement on Ukraine concluded without its participation" 1. Second: Ukraine must preserve its territory — a direct rejection of Russia's demand that Kyiv cede four oblasts before negotiations continue .
The current trilateral format excludes all 27 EU member states. The collective European contribution to Ukraine's defence — in financial aid, weapons transfers, refugee absorption, and energy restructuring — exceeds the American contribution. France and the UK pledged troops as security guarantors at the January Paris summit. Germany has not, and Merz faces a constraint his counterparts do not: the Bundestag holds a constitutional bar on combat deployments abroad without parliamentary approval. No such vote has been scheduled.
Merz has no seat at the negotiating table, but his leverage lies in what happens after any deal is signed. EU sanctions relief for Russia, European reconstruction funding for Ukraine, and any European troop deployment as part of a monitoring force all require European political endorsement. Trump can broker a ceasefire. He cannot deliver a durable settlement that Europe refuses to implement. The second Abu Dhabi round showed the limits of a format that negotiates territory and monitoring without the parties who would enforce and fund the outcome . Merz's visit did not change the format. It stated the cost of excluding Europe: an agreement that cannot be made to work.
