My solution to the problem of unleashing creativity is always to set up a target. The best example of this was the Apollo project in the United States.
What the United States has to do is send a clear message to Iran that they will not be able to develop nuclear weapons. Why endure the difficulty of sanctions if they are not going to be able to develop nuclear weapons anyway?
Hip-hop went through different stages, from the beginning in the streets of the Bronx, to the whole Tri-State area and then to the rest of the United States and the rest of the world.
I was distressed that after 9/11, when the United States was attacked by terrorists, the United States' response was to attack Afghanistan, where some of the terrorists had been.
It is my firm belief that it will be in the interests of the United States, especially our economic interests, to pursue comprehensive immigration reform.
It's a moral imperative, it's an economic imperative, and it is a security imperative. For we've seen how spikes in food prices can plunge millions into poverty, which, in turn, can spark riots that cost lives, and can lead to instability. And this danger will only grow if a surging global population isn't matched by surging food production. So reducing malnutrition and hunger around the world advances international peace and security - and that includes the national security of the United States.
It is in the interests of all of us - the United States, China and the rest of the world - to make sure that the rules of the road are upheld. These rules and norms are part of the foundation of regional stability, and they have allowed nations across the region, including China, to grow and prosper.
Compared with how we've ducked it in the United States, Canada should be really proud of how you have welcomed a significant number of refugees - far more, in fact, than we Americans have, even though our population is vastly larger.
The United Kingdom and the European Union will remain indispensable partners of the United States even as they begin negotiating their ongoing relationship to ensure continued stability, security and prosperity for Europe, Great Britain and Northern Ireland, and the world.
