Even though this point correctly presents a theoretical possibility, the reality is different. Europe has since come up with an alternative solution that means the need for unanimity does not always mean decision-making can be slowed by a spoiler; the opt-out. Countries can negotiate to opt out of further integration on areas where they believe their national interests are threatened. This then allows all the other states to carry on with integration without risking a veto from the states that do not wish to follow that path. What further corroborates this point is that since Luxembourg accord, nothing similar has ever occurred, and even the compromise allowing for invoking national interests to halt QMV is no longer used. Thus it is irrational to fear “empty chairs” now, when all the states are aware of the possibility of a stalemate, and would, perhaps, never wanted to be held accountable for such situation.
