I'm not in favour of a regulation-free world. I align myself with Teddy Roosevelt, who broke up the trusts. Regulation is necessary, but it should be in favour of the consumer, the citizen, and freedom.

The sanctions and travel restrictions would have to be far more comprehensive to be truly painful for [Vladimir] Putin and his inner circle. And the new middle class should also feel the effects of what he is doing. For instance, we should ask those who wish to enter the EU whether they have visited illegally occupied Crimea in the last few months and, if the answer is "yes," deny them a visa.

If you're already in a fight, you want the first blow to be the last and you had better be the one to throw it.

Donald Trump is a catalyst. People care now in a way they didn't. The American institutions were rusting; now they are being revitalised. Trump is a lightning rod. They are getting engaged and the American liberal media that spent too much time on PC issues can focus on Vladimir Putin and Recep Tayyip Erdogan.

The regime is in trouble economically and can no longer offer anything to its citizens. That's why [Vladimir] Putin has to pursue an aggressive foreign policy, so he can serve his people the fairy tale of Russian pride and regaining its strength as a major power.

Many Republicans who traditionally were for a positive role in the world, anti-Russian, now they want to defend their party and leader, and they don't care about real arguments. The paradox is the Democrats were so timid in criticising Vladimir Putin. Barack Obama appeased him and now they are criticising Putin's interference in American democracy. It is a strange reversal of the roles.

Inevitably the machines must win, but there is still a long way to go before a human on his or her best day is unable to defeat the best computer.
