My heart goes out to the Chinese people. Our system is flawed, but it's one where even the most powerful of abusers can fall.

The next century of competition is looking incredibly interesting.

America made incredible leaps forward in WWII and the Cold War in the face of stiff competition. When our rivals disappeared, we only made incremental improvements in the decades that followed. We wasted our attention on distractions.

Now we're once again facing a challenging and ideologically opposed rival that will force us to focus more than ever before.

Let's hope that freedom and democracy endure.
