Even with a BMD system in place there is no gurantee that it can actually and in a full proof manner defend against sophisticated threats and there are many ways to skin the cat , the iranians are no dumb either.
One of the disadvantage of building an ABM and if it it in reality works 50 % as advertised , it forces the enemy to increase exponentially its offensive potential because he ends up thinking it works 100 % as advertised , so Europe can build bigger and better ABM but Iran will end up building more sophisticated IRBM of Shahab-3/Sejil class.
In the end Europe will not be secure building bigger BMD system even if we leave the russian angle
Eventually any ambitious plans would unnerve Russia and China and they would respond in some ways specially Russia , a lot of its is also politics and struggle for sphere of influence.
