And how would a missile defense shield in Poland or the Czech Republic help the people in the countries in Europe that lie between them and Iran? Or are we only concerned with some countries and not others?

And if the shield can only take down a small number of missiles, what would stop a "rogue state" from launching a couple of dozen missiles with no nuclear warhead on them, and waiting until they've been shot down before launching the ones with the nuclear payload?

I'll never believe that our people haven't thought of that possibility.   So that would mean that either they have planned for that and the shield can take down a lot more missiles than they're saying (which would make it an offensive weapon against Russia), or the people who are designing this system are too stupid to be playing with explosives. Or they're just lying about the shield actually being of any benefit whatever, and the "missile defense shield" is just another way to rip off the US taxpayers. I'm inclined to believe it's all three, myself.
