This is how Adolf Hitler would have NOT started, he waited a couple of years.
Griffin was collared by a news team and he developed an argument that he would use weapon's strike to sink vessels carrying 'illegal immigrants', and then chuck life rafts in after them. Since when does bombing vessels for immigration purposes not constitute an act of war? This is not a proportionate response to a perceived threat of Illegal immigration. How do the constituents who voted for him react to this method?
Is there anything about his outburst that indicates a crime has been committed? What if he does not have enough Lifebelts or Lifeboats, will there be a head count before the boat is torpedo'd?
