Maybe the value of lying in politics and business?

From Heather Cox Richardson latest Monday post. I would go on to note that MAYBE Trump teaches us that lying is not always bad, that when our adversaries get used to us lying, it gives him (or 'us') power to hit them any way we want, to keep them unsure and unsteady. That's maybe also his strength. Like a car salesman (or 'real estate' salesperson) who you know might be lying, but since you want to car (or house) you still deal with them. To quote: " Krugman goes on to make a major point: “Think about how much America’s position in the world has been weakened, not just by apparent failure to subdue a fourth-rate power, but by the fact that everybody now knows that you cannot trust anything, cannot trust any promises the United States makes, you cannot count on the United States carrying through with promises, with threats, not just promises, but threats are also incredible in the sense of not being all credible, and that the default assumption should be that anything that this administration says is a lie.” "
