Unity is strength
Not sure I understand this debate in its entirety. However if we believe that we may have to fight major regional powers (i.e. Russia and/or China) then we have to have carriers complete with fast jets. Whether they are RN or RAF is a matter for the experts but we will need them. What I worry about is that we spend too much time arguing about how big our slice of the pie is, rather than arguing about whether the pie is big enough to meet our needs.
