BMD Missiles to Europe

Senator Bill Frist wants to send a message to Iran, according to Fox News:

In the letter, Frist sought to send a signal to Iran that the United States is committed to countering that country's nuclear ambitions. At the same time, the potential presidential candidate aimed to show that he's strong on national defense, which could be a major issue in the White House race two years from now.
Putting interceptor missiles at a site in Europe would significantly enhance the United States' ability to protect against ballistic missiles launched from Iran, Frist said in the letter.
"As Iran continues to make progress in deploying its Shahab 3 missiles and developing new, longer range missiles, while simultaneously pursuing nuclear weapons, the ability to shoot down Iranian warheads in flight becomes increasingly critical to our national security," Frist said.

Actually, I'm thinking it would concern Russia more than the mullahs in the next continent.
