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.

I'm kind of old-fashioned because I was born and live in the same house for six generations.

Ancient wisdom: deal in personal trust; your word is your bond; avoid extremes; treat the money you invest for others as something sacred; don't take any more perks than you would wish others to take; don't borrow what you couldn't suddenly pay back; imagine the worse case financial scenario and expect it very may well happen; the wealthier you become the more humble you should act.

Western societies from ancient Athens to imperial Rome to the French republic rarely collapsed because of a shortage of resources or because foreign enemies proved too numerous or formidable in arms - even when those enemies were grim Macedonians or Germans. Rather, in times of peace and prosperity there arose an unreal view of the world beyond their borders, one that was the product of insularity brought about by success, and an intellectual arrogance that for some can be the unfortunate byproduct of an enlightened society.

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.

I think there's a group of students - whether it's the micro-aggression or the safe space or the trigger warning that garner a lot of attention - but that the fundamental issues that they're more interested in are - and I'll be very frank here - how much money do I pay for a unit? And what is that unit going to do for me when I'm graduating?And even though this is mostly in a progressive landscape, they're asking questions that have not been asked of the university. And the university can't supply answers to them.

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