That is certainly the most relevant subject for the UK, but it is also the most difficult to evaluate objectively. Are you being a jingoist? Are you overcompensating? Are you on target? The way to to that is to see it all from the argentinian perspective, and then let their voices speak, and not express too much sentiment one way or the other. These are their views, i am not responsible for them and so on. If you do it another way, you are writing about thatcher and British history, and not about latin american culture. What our veterans saw etc. A great, but different subject.
