Agree with Stop/Start to a degree, something should be done. However, Belgium contibutes very little militarily to the EU, and the Congo is their former stomping ground.
All for military intervention, but their are many nations with troops doing nothing at the moment. Belgium, Germany, Hungary, Greece, Italy and others are happy to slumber peacefully under the NATO blanket, but are slow to contribute (Standfast the German deployment to ensure the airfield at Kabul is safe for parties and beercalls).
