If Russia is there [in Syria] alone fighting them [ISIL], guess what? Russia becomes the target and Russia starts seeing - who knows - MANPADs will find their way in there, airplanes will fall out of the sky. They will become vilified. They'll become the new magnet, together with Assad, for the jihadis.

What we do right now, today, matters.

If the threat is jihadism - and it is - and the threat is the destruction of Syria so that all of these refugees are swamping into Europe and changing the whole character and politics of Europe, this is the time to unite to find a way out.

President Clinton was often known as the first black president. I wouldn't be upset if I could earn the right to be the second.

I think it's time we had a President who will provide the only real economic security: good jobs. A President who will provide middle class payroll tax relief to get money in the pockets of workers who will spend it, not more tax giveaways for those at the top to stimulate the economy in the Cayman Islands and Bermuda. A President who will index the minimum wage to inflation and raise it from a 30 year low, not increase the tax burden on the middle class and those struggling to join it.

I do think that it's really important for leaders of countries to be very clear and careful in the statements they make because their words are weighed extremely carefully by other countries, and you have to create a continuity of seriousness and of credibility in order to be able to be taken seriously and get things done.

America must always be the world's paramount military power. But we can magnify our power through alliances.
