We cannot allow this ideology the safe space it needs to breed. Yet that is precisely what the Internet, and the big companies that provide Internet-based services provide. We need to work with allied democratic governments to reach international agreements that regulate cyberspace to prevent the spread of extremist and terrorism planning.
And we need to do everything we can at home to reduce the risks of extremism online. There is, to be frank, far too much tolerance of extremism in our country. So we need to become far more robust in identifying it and stamping it out across the public sector and across society.
So in light of what we are learning about the changing threat, we need to review Britain's counter-terrorism strategy to make sure the police and security services have all the powers they need. And if we need to increase the length of custodial sentences for terrorism related offenses, even apparently less serious offenses, that is what we will do.
Since the emergence of the threat from Islamists inspired terrorism, our country has made significant progress in disrupting plots and protecting the public. But it is time to say enough is enough.
