NATO chief vows response to Russian missile pact violations NATO Secretary-General Jens Stoltenberg says the military alliance will respond to Russia's violation of a key Cold War-era treaty but will not station more nuclear missiles in Europe

BRUSSELS -- NATO's secretary-general warned Tuesday that the military alliance will respond to what it insists are Russia's violation of a key Cold War-era treaty but will not station more nuclear missiles in Europe.

Jens Stoltenberg urged Russia to return to compliance with Intermediate-Range Nuclear Forces (INF) treaty it agreed bilaterally with the United States in 1987. On Feb. 2, Washington launched the six-month process of leaving the INF, insisting that a missile system Russia calls the Novator 9M729 — known at NATO as the SSC-8 — breaks the pact's range requirements.

The INF bans production, testing and deployment of land-based cruise and ballistic missiles with a range of 500-5,500 kilometers (310-3,400 miles).

"Any steps we take will be coordinated, measured and defensive, and we do not intend to deploy new ground-based nuclear missiles in Europe," Stoltenberg told reporters at NATO headquarters in Brussels on the eve of a meeting of allied defense ministers.

Stoltenberg said the ministers will discuss Wednesday "what steps NATO should take to adapt to a world with more Russian missiles." He declined to say what measures are being considered.

"Moscow continues to develop and deploy several battalions of the SSC-8 missile," Stoltenberg said. "We all know that a treaty that is only respected by one side cannot keep us safe."

The Pentagon believes that Russia's ground-fired cruise missile could give Moscow the ability to launch a nuclear strike in Europe with little or no notice.

Russia insists it has a range of less than 500 kilometers, and claims that U.S. target-practice missiles and drones also break the treaty. President Vladimir Putin has announced that he is pulling Russia out of the INF too.

European NATO members are especially keen to avoid any nuclear buildup and a repeat of the missile crisis in the 1980s. NATO allies decided to deploy U.S. cruise and Pershing 2 ballistic missiles in Europe in 1983 as negotiations with Moscow faltered over its stationing of SS-20 missiles in Eastern Europe.

The U.S. ambassador to NATO, Kay Bailey Hutchison, sought to reassure them.

"Our allies want to know what the future will be, and the future will be that we will start the development of a defensive mechanism and we will keep our allies informed all along the way. We will consult at every turn," she said.
