[Current Affairs Analysis] The US and Ukraine reached a consensus in Berlin regarding the "90%" proposal.
The US and Ukraine reached a consensus on "90%" in Berlin, but this mainly involves institutional arrangements such as security guarantees, military aid coordination, and reconstruction. The real obstacle is the territorial status, which cannot be technically addressed. The West attempted to stabilize the controllable 80% in Ukraine with a "like Article 5" agreement, but Kyiv insisted on not ceding territory or recognizing the aggression, while Moscow insisted on legal recognition as a prerequisite for peace, leading to a structural confrontation between the two sides.
Therefore, "90%" signifies the initial formation of a framework for the system, but does not represent a peaceful approach; the remaining 10% sovereignty issue is the core factor determining whether the agreement can be implemented. The next step will test whether the international community can build sustainable security and economic support for Ukraine without recognizing the use of force to change the borders, and will also be a stress test for the European security order.
