Look north to find the front line of North America’s defense
By: Gen. Terrence O’Shaughnessy  
As the commander of North American Aerospace Defense Command and U.S. Northern Command — two distinct commands with complementary missions and capabilities — my top priority is the defense of the United States and Canada. In recent years, the front line of homeland defense has shifted north. The Arctic is a potential approach for our adversaries to conduct strikes on North America and is now the front line in our defense.
The defense of our nations depends on our ability to detect and defeat attacks on Canada and the United States wherever they arise. Achieving the capabilities necessary for military operations in the Arctic requires deliberate engagement and coordination with key stakeholders, and we are rolling up our sleeves and driving solutions to meet the inherent challenges of Arctic operations.
