Any country which conducts it commercial business over the deep blue sea, needs a carrier to protect their interests & free trade. How-ever they are an expensive piece of kit. 99.9% of the time you won’t really need one so the bean counters won’t give you one, then when you really need it their arn’t any and you end up spending more dosh replacing everything you have lost.
It’s the British way of doing things! (commie, socialist, liberal, establishment way to be exact)!!!

do mean all countries im sure Cuba need’s one and the Caribbean nations:dev2:. I see a Carrier as necessary if your country is an expeditionary nation and needs air support off shore. Of the listed nations Brazil is the one i have issues justifying as they have an old fleet of frigates which could be replaced or updated with the maint budget of San Paulo
