How divided is Europe over war with Iran?

TVNet says it’s clear that the E3, aka Germany, France and the UK, and not the EU, has taken the leading role:

“This dynamic is reminiscent of previous crises in which European security policy was controlled not by the institutional centre in Brussels but by a core group of major powers. If the E3 were to take on a more active role, this could mean the de facto establishment of a new security centre in Europe – with France and Germany as the political axis and the UK as a militarily strong partner outside EU structures. … The question is: is this a temporary solution in a crisis or a structural change in the European security architecture?”
