The real reasons for the High Command being all Evil Brits was twofold. One, Lucas blew his budget on the cantina scene, so he didn't have the makeup budget to make alien commanders for that scene. Two, there was a law at the time stating that filmmakers working in the UK had to have a certain percentage of British actors in their production. Lucas decided to put his "required percentage" of UK actors around the villains' table as a way of showing what he thought of those quotas.
