1) From Bruce Schneier, renowned and sensible expert on taking terrorist threats seriously without overreacting and defeating ourselves in the process, on exactly which aspects of the Chinese "hacker" menace are worrisome, and which ones aren't.
Executive summary: these hackers aren't controlled by the Chinese government or military and basically are sharp, cocky young men showing off their technical skills. "The hackers are in this for two reasons: fame and glory, and an attempt to make a living." That is reassuring in some ways and not in others. But the essay should be read in full. (Thanks to Edward Goldstick for tip.)
2) From one Barack Obama, on the mixture of military strength, non-military influence, assertiveness, and restraint that will advance American interests in this era of ongoing terror threats, ongoing Iraq and Afghanistan combat, financial and economic chaos, resource and energy crises, rise of China, unruliness of Russia, and so on. Full text and some video here.
Executive summary: any speech that begins and ends with allusions to George C. Marshall's vision 60 years ago is quoting the right authority but setting a high standard for itself. This is a speech rather than a whole implemented years-long program, in contrast to the great Marshall's achievement. But as a speech it stands up very well and deserves to be read and absorbed in toto rather than relying on news clips.
