The Yuuzhan Vong believed that all other races were little more than barbarians who were not fit to live in their presence. Because of this the Vong attempted to conquer the universe with little thought to the damage they were doing to the universe or its inhabitants. The only race the Vong saw as a threat, or as close to a threat as they were willing to believe, were Wookiees. They saw them as fierce warriors and felt that they deserved to live. For this reason, the Vong enslaved Wookiees rather than attempting to destroy them.
