6. Aircraft carriers -too expensive and too vulnerable!
12. United Nations - waste of time ??
When was the last time an aircraft carrier was damaged in battle? 1945? Granted we have not had a major blue water peer conflict, but carriers seem to have come in handy over the last 75 years in conflict large and small. As for expensive, it is only too expensive if you can't afford it. A Ferrari is to expensive for me, but maybe not the next guy.
UN. Perhaps more talk than action, but would prefer that there is no international body? I think it is good to have a forum.
