I keep reading that the bulk of the Czech and Polish populatons are very much opposed to a US missile defense shield…so, why (really? why?) should the US invest gazillions dollars building it so as to defend eastern Europeans against some errant missiles from Iran? Meanwhile, the Czechs and Poles would have to put up with an irate Russia threatening the Czechs and Poles (if the shield goes up)…(I don’t see a clear American interest here…)
