Article 5 Ten Years On: Division or Unity?

By Simona Kordosova

Ten years ago, in the aftermath of the 9/11 terrorist attacks, NATO invoked Article 5 for the first and only time in its history. Paradoxically, a treaty provision created to guarantee American assistance in case of a Soviet attack on Europe instead brought Europe to the aide of the United States in Afghanistan. Since then, […]

NATO Support Steady Through Transatlantic Twists and Turns

By James Joyner

The German Marshall Fund has just released its annual Transatlantic Trends report, which measures U.S. and European public opinion on transatlantic issues and trends. The big headline is that a bare majority of Americans, 51 percent, now think the countries of Asia are more important to their national interests than the countries of the European Union, which […]

International Partnership and NATO’s Future in Afghanistan

By William B. Caldwell IV

Reflecting on ten years of United States involvement in Afghanistan, the greatest long-term effect the international community can have in Afghanistan is through continued partnership. Today, nearly a quarter of the world’s nations are working with the Afghan government to rebuild a war-torn society, stimulate economic activity, and develop their security forces. In spite of […]

Being NATO’s Secretary General on 9/11

By Lord Robertson

But on 11 September, 2001, Lord Robertson had one of the most extraordinary experiences of any NATO Secretary General. Here, he recounts how the day panned out. At NATO Headquarters in Brussels, it was just an ordinary Tuesday. One which was to […]

Cyber Attacks Against NATO, Then and Now

Now that NATO’s Operation UNIFIED PROTECTOR over Libya is winding down, it is worth noting how few cyber incidents were directed in protest against the Alliance.

Global Con?

By Arnaud de Borchgrave

Were the United States, France, Britain, Belgium, Denmark, Norway, Qatar and the United Arab Emirates — the NATO-led coalition that set out to overthrow Col. Moammar Gadhafi’s regime — snookered by al-Qaida? A preposterous scenario with some disturbing factual elements. In the early 1990s, when James Woolsey was the director of the CIA, Gadhafi appealed […]
