Global security can be formed or threatened by heads of state whose wisdom, folly and obsessions shape global events. But often it is the security practitioners, those rarely in the headlines but whose craft and energy quietly break new ground, who keep us safe or put us in peril.
Tonight, I ask for your prayers for all those who grieve, for the children whose worlds have been shattered, for all whose sense of safety and security has been threatened. And I pray they will be comforted by a power greater than any of us, spoken through the ages in Psalm 23: "Even though I walk through the valley of the shadow of death, I fear no evil, for You are with me."
The country that owns green, that dominates that industry, is going to have the most energy security, national security, economic security, competitive companies, healthy population and, most of all, global respect.
Global energy security is a vital part of America's national security.
Actually, the phrase "national security" is barely used until the 1930s. And there's a reason. By then, the United States was beginning to become global. Before that the United States had been mostly a regional power - Britain was the biggest global power. After the Second World War, national security is everywhere, because we basically owned the world, so our security is threatened everywhere. Not just on our borders, but everywhere - so you have to have a thousand military bases around the world for "defense."
I would argue that we have a patriotic duty to move toward energy independence and clean energy. It is a matter of national security - energy security, climate security, economic security, job security, everything.
We need a global parliament, a global government and possibly a global ministry for security.
The stability of global financial markets is a public good. If governments fail to protect this public good, then those who suffer are the working people of the world whose jobs, whose homes, and whose standard of living depends on it.
The Security Council should be seen as the executive committee of the global security system set up after World War II. Its members, and especially the Permanent 5 (P5), have a special responsibility for international peace and security.
Defending against military-strength malware is a real challenge for the computer security industry. Furthermore, the security industry is not global. It is highly focused in just a handful of countries. The rest of the countries rely on foreign security labs to provide their everyday digital security for them.
Rarely have Americans lived through so much change, in so many ways, in so short a time. Quietly, but with gathering force, the ground has shifted beneath our feet as we have moved into an Information Age, a global economy, a truly new world.
The whole idea from some of our opponents that armed security makes us less safe is completely ridiculous. If that's true, armed security makes us less safe, let's just go ahead and remove it from everywhere.
In New York - whose subway trains in particular have been "tattooed" with an energy to put our own rude practitioners to shame - not an inch of free space is spared except that of advertisements.
Food security is a global problem, with real and immediate effects on national security.
Our approach [to global security] has changed by the way we've elevated development. The biggest lesson is to recognize global responsibility.
Is real, it is serious, it is growing, and it constitutes one of the greatest threats to our national security and, indeed, to global security.
But Australia faces additional regional and global challenges also crucial to our nation's future - climate change, questions of energy and food security, the rise of China and the rise of India. And we need a strong system of global and regional relationships and institutions to underpin stability.
