No. Missiles headed to the U.S. from Russia come over the pole. They don't go over Europe.
While you are of course correct about this, the radar stations set up in Poland and the Czech Republic can monitor the skies over eastern Russia to include all their ICBM bases. In the event of a Russian launch they will pass targeting info to Ground-based Missile Defense(GMD) installations in Alaska and California, which will destroy the second stage warhead bus over the pole before the warheads and their decoys deploy. The Russians know this. That's why they're dead set against those radar installations ever coming on line.
