Sullivan employs not a transparent strategy, but instead, after taking charge, he launched a full-scale offensive against Gao Guang in an upright and formal manner.
An uninvited righteous banner, do not attack a grand formation; such are the agents of change.
When Sullivan realized that King's Defense was a deeply-rooted interest group with extensive ties, he knew that just getting rid of Gao Guang wouldn't be enough.
Raising the banner of proper political practice, using a grand formation to encircle and block Gao Guang's forces, as long as they were forced to abandon him, there would be no more issues. However, such an endeavor required mobilizing a tremendous amount of resources. Sullivan simply felt that dealing with just Gao Guang was not worth the political cost.
Sullivan is restrained and pragmatic; he does not harbor a deep hatred towards Gao Guang, and hence only wishes to resolve the matter with the least cost and in the quickest way possible.
