The bible. The bible. It may not beat out the bible. But Donald Trump has been pushing his book, "The art of the deal" throughout this campaign, to boost his bona fides as a leader.

It made us wonder, does his experience with the give and take shape his approach to world affairs. "The art of the deal" trump's best-selling, chest-thumping business how-to from the go-do '80s. The title winks at the ancient battle book, "The art of war." Almost 30 years later, is his best-seller a blue print? In his speech on Wednesday, the gop front-runner laid out international relations under president trump. It is the cheapest single investment we can make. In negotiation, you must be willing to walk. Reporter: Sounds a lot like business relations under trump, the CEO. Just look at China. No talk of democracy. Human rights. Trump's beef is he thinks our trade imbalance is caused by Chinese currency manipulation. We have the leverage, the power. Over China. Economic power. Reporter: Or as he put it a few years ago zsh. What can you do. So easy. Listen you , we're going to tax you 25%. Reporter: As he put it in "The art of the deal" sometimes it pays to be a little wild.

They're going to build the wall and Mexico is going pay for the wall. And you know it. And I know it. And they know it. Reporter: Does trump's book hint we should take it all with a grain of salt?
