From the New York Times: Last week, President Obama — on my recommendation and with the advice of his national-security team and the unanimous support of our senior military leadership — decided to discard that plan in favor of a vastly more suitable approach. In the first phase, to be completed by 2011, we will deploy proven, sea-based SM-3 interceptor missiles — weapons that are growing in capability — in the areas where we see the greatest threat to Europe.

The second phase, which will become operational around 2015, will involve putting upgraded SM-3s on the ground in Southern and Central Europe. All told, every phase of this plan will include scores of SM-3 missiles, as opposed to the old plan of just 10 ground-based interceptors. This will be a far more effective defense should an enemy fire many missiles simultaneously — the kind of attack most likely to occur as Iran continues to build and deploy numerous short- and medium-range weapons. At the same time, plans to defend virtually all of Europe and enhance the missile defense of the United States will continue on about the same schedule as the earlier plan as we build this system over time, creating an increasingly greater zone of protection . . .

This proposal is, simply put, a better way forward — as was recognized by Prime Minister Donald Tusk of Poland when he called it “a chance for strengthening Europe’s security.” It is a very real manifestation of our continued commitment to our NATO allies in Europe — iron-clad proof that the United States believes that the alliance must remain firm . . .

The bottom line is that there will be American missile defense in Europe to protect our troops there and our NATO allies. The new proposal provides needed capacity years earlier than the original plan, and will provide even more robust protection against longer-range threats on about the same timeline as the previous program. We are strengthening — not scrapping — missile defense in Europe. (photo: Haraz N. Ghanbari/AP)
