The United States and Russia are sending teams of software, and missile defense, experts to each others military facilities to conduct joint training anti-missile exercises. Both nations are exploring ways to combine their anti-missile defense efforts with those of other NATO nations. Although Russia is on good terms with Iran right now (because Russia is providing Iran with nuclear power plant technology), Russia also knows that hard liners among the Islamic conservatives that control Iran would love to fire a nuclear tipped missile at Russia. Theres also the danger that Pakistan might fall under the control of Islamic radicals. So effective ballistic missile defense is something both nations, and many others in Europe as well, are interested. Next year, Russian technical teams will come to the United States to conduct more joint missile defense simulation exercises.
