Marietje Schaake, International Policy Director at Stanford's Cyber Policy Center, Eurasia Group senior advisor and former MEP, discusses trends in big tech, privacy protection and cyberspace:

After an attempted hack of a Republican National Committee contractor, is cybersecurity at a breaking point between the US and Russia?

Well, that breaking point has been a long time coming. There was the attempt to manipulate the 2016 elections and now we see a series of ransomware attacks that are escalating. So the question is, what the US can do to decisively change the calculation on the Russian side? Making clear that there will be sanctions and other consequences that hurt should be a start. But it will only be credible if these promises are followed through and enforced.
