While I understand the passions and the anger that arise over the death of Michael Brown, giving into that anger by looting or carrying guns, and even attacking the police only serves to raise tensions and stir chaos.

You know, it's fashionable right now for people to be cynical. We go in cycles like this and right now a lot of people are saying, 'Oh, America is doing terribly' and 'What are we going to do?'

We wouldn't even be where we are had it not been that 70% of Hispanics voted for President Obama, voted Democratic in the last election. That caused an epiphany in the Senate, that's for sure. So all of a sudden we have already passed comprehensive immigration reform in the Senate. That's a big victory.

I think that Mr. Snowden raised some legitimate concerns. How he did it was something that did not follow the procedures and practices of our intelligence community. If everybody took the approach that I make my own decisions about these issues, then it would be very hard to have an organized government or any kind of national security system.

The old rules may say we can’t protect our environment and promote economic growth at the same time, but in America, we’ve always used new technologies - we’ve used science; we’ve used research and development and discovery to make the old rules obsolete.

But the question is, do we care enough? Do we care enough to keep standing up for the country that we know is possible, even if it's hard, and even if it's politically uncomfortable? Do we care enough to sustain the passion and the pressure to make our communities safer and our country safer? Do we care enough to do everything we can to spare other families the pain that is felt here today?

Here in Europe, I think that there are a lot of young people who forget the issues that were at stake during the Cold War.
