Compare this article to advice from a famous Diplomacy player (http://diplom.org/Zine/F1997R/Windsor/lawdip.html):

1. Always Start With Your Own Proposal

2. Make Detailed Proposals

3. Clearly State Mutual Responsibilities

4. Be Prepared to Give Meaningful Consideration

5. State the Penalties for Breach of Contract

6. Be Prepared to Walk Away from the Table

Agreed, this is terrible advice. Negotiations are meant to be a method for two parties with similar goals to understand the needs of the other party and present an opportunity for everyone to walk away happy.

Paul seems to think that negotiations are best when you screw the other side over. Or he's defensive and believes that "since they are trying to screw me, I'll screw them."

Most negotiations are just the start of an ongoing and lasting relationship with the other party, do you really want to be trying to "screw them over?"
