The tactic is to expand the number of constituencies from whom you need a "Yes" from so that you are certain to get a "No". Abbas did this by joining with Hamas. Bibi did this first be refusing by refusing to concede any point (borders for example) until all points were agreed to. You may get a majority of your government to support your position on one point, but rarely on all points; you can get agreement more easily by going point by point, rather than all points at once. Here's an example. Ten years before the U.S. Civil War, Henry Clay proposed the Compromise of 1850 as a package deal to Congress, and it went down to defeat. Stephen Douglas broke down the package into its constituent parts and got a majority to back each individual part and got it passed. The majority willing to back one part was different from the majority willing to back another, and that's how he got the whole bundle passed. Apparently, Bibi refused to do that, and apparently, he got the result he aimed for.
