The term 'First EA-PLANT War' is stated in the manuals of the High Grade Freedom Gundam model kit as well as the Master Grade Strike Rouge Ootori model kit. SO IT IS DEFINITELY LEGIT. And AFAIK, the term 'Bloody Valentine War' is also not mentioned in the show. The user Redcrimson300 claim otherwise, i will be waiting to be proved wrong. Until then i stand my ground that the war in Gundam seed is called ' FIrst EA-PLANT War'.
