They aren't offensive weapons systems. They are strictly defensive missile shields. To prevent attack, prevent a rogue launch, or mulitiple other scenarios. They have no offensive capabilities.

You should be asking not why are we helping Western Europe install this shield, they have a right to be prepared defensively for any scenario, but why are the Russians so adimant it isn't put in that they are willing to threaten the countries that have them put in, along with the US.

There is no such thing as a defensive weapons system. If I prevent you from being able to attack me, that is offense. You must devise an alternate scheme to "balance the scales." You know that.
