The problem with deterrence - apparently sometimes forgotten by our former presidents - is that it is not static, but a creature of the moment, captive to impression, and nursed on action, not talk. It must be maintained hourly and can erode or be lost with a single act of failed nerve, despite all the braggadocio of threatened measures. And, once gone, the remedies needed for its restoration are always more expensive, deadly - and controversial - than would have been its simple maintenance.

The president who is most slandered as Hitler will probably prove to be the most zealous advocate of democratic government abroad, the staunchest friend of beleaguered Israel, and the greatest promoter of global individual freedom in our recent memory.

Entertainers wrongly assume that their fame, money, and influence arise from broad knowledge rather than natural talent, looks, or mastery of a narrow skill.

Stop seeing socialists and anti-Americans as Democrats. When a Michael Moore compares beheaders to our own Minutemen and laments that too many Democrats were in the World Trade Center, he deserves no platform alongside Wesley Clark or a seat next to Jimmy Carter or praise for his pseudo-dramas from high Democrats.

If I talk to black students on campus, they're not sympathetic to the people who are not sympathetic with [Black Lives Matter movement]. The fact that you want to argue rather than find some common ground, I think, has gotten a lot worse in the last years.

The fact is that we have been consistent in a predictable 60-year commitment to national security, while our friends and former enemies - by intent or default - have followed different paths since 1989. We stayed mostly the same as they became hypopowers that, to take a small example, would and could do nothing should a madman in Korea wish to kill millions.

Any time the Western way of war can be unleashed on an enemy stupid enough to enter its arena, victory is assured.
