The appearance of weakness has emboldened our adversaries, who believe they can attack the United States in cyberspace with impunity.

Threats to the United States in cyberspace continue to grow in scope and severity, but our nation remains woefully unprepared to address these threats.

I want to raise another important international law issue, and that's the meaning of sovereignty in cyber.

Well, I thank you, but this is really--you raise several fundamental questions that have to be resolved by the Congress and the American people.

the United States will respond to cyber attacks. The question is not whether; the question will only be how.

If you destroy the election system of a democracy, if you destroy it, then you have basically dealt an incredible blow to that country which is probably far more severe than shutting down an electrical grid.

It says we created this government, us, for the common defense of this nation, and we aren't doing that job.

If an enemy or an adversary is capable of changing the outcome of an election, that's a blow at the fundamentals of that country's ability to govern, right?

we should also respect the fundamental right of Americans to privacy.

Given what happened last year, it seems clear that we need cyber deterrence, not just defense but deterrence as well.

it's not easy.
