What we Americans need to do is respect that incredible blessing that we have as a nation and make sure that we are leading in the best ways possible.

There is no bigger judgment for a president of the United States than how you take a nation to war.

Where are they now that we, the men whom they sent off to war, have returned? These are commanders who have deserted their troops, and there is no more serious crime in the law of war. The Army says they never leave their wounded. The Marines say they never leave even their dead. These men have left all the casualties and retreated behind a pious shield of public rectitude. They have left the real stuff of their reputation bleaching behind them in the sun in this country.

America has not led but fled on the issue of global warming.

America has everything most countries envy. A Constitution which is the treasure of mankind, a strong military, natural resources of every kind. Above all, as Tocqueville said, a good people, which is what makes us great.

I met with many of - a number of [Syrian] refugees in Berlin the other day, and I was struck by how educated, intelligent, and patriotic they are. They want to go back. They love their country. And there are so many of them still in Jordan and in refugee camps in Lebanon and in Turkey, that if you could create the climate within which they could begin to come back, I believe there is such a history of secularism within Syria, even tolerance within Syria, that if we can deal with ISIL, yes. That's the key. And with ISIL there, not a chance.

We do have to take the long-term view. And long term, the question to ask ourselves is whether America should attack others pre-emptively, whether she should embroil herself in wars far away from our soil, and try to bring democracy by force to the rest of the world.
