Operational cooperation is a key element of the EU migration policy. It is thanks to the databases and mechanisms set up by EU institutions that Member States can exchange valuable data and information to tailor their migration strategies. After the Russian full-scale invasion of Ukraine, the EU launched the Solidarity Platform to support the Member States in the uniform implementation of the Temporary Protection Directive. In the first year since its launch, the platform has grown in the number of activities and objectives tackled, thanks to the political will of the Member States and its legal flexibility. Given the success of the Solidarity Platform in filling the gaps in the EU operational crisis response, it is worth questioning whether the mechanism can become a permanent tool of the EU migration policy.
