Just heard Bulgaria has become the latest EU member to reassert its sovereignty against the EU by joining the Visegrad Four and Austria in their calls for the closing of Europe to migrants and a steadfast refusal to accept any migration quotas imposed by Brussels. So with an increasing number of member states openly stating they will not comply with EU policy regarding migration, it got me thinking: How exactly does the EU plan to deal with rebellious member states? You can't kick them out because as far as I'm aware, there are no provisions for forcibly removing a member from the EU and removing member states also diminishes the EU's power and influence just like removing a state from the US would diminish its power and influence. You can't suspend their voting rights either because, well, what the hell is that going to do to convince a member that already isn't following your rules? I mean, let's say Brussels tells Bulgaria they MUST take in 50,000 refugees and starts sending migrants their way. In response Bulgaria deploys its army to the border with orders to detain and deport any migrants or refugees that attempt to cross. In such a situation, what precisely could the EU do to force Bulgaria to stand down and comply with EU policy?
