I 'd agree with all of that Kinky.
The only thing I would have any issue with is;
Today it is the intention of Sinn Fein/IRA to obtain the conviction of at least one British Soldier from the 1970's. In so doing they will feel that the single conviction will justify the fifty thousand casualties that they inflicted on the people of Ulster during Operation Banner.
Whilst true it would suit Sinn Fein, I don't think it's the motivation of the BSJC. And I certainly don't associate your second sentence with their goals.

Also;
The soldiers weren't to blame for 'the troubles' - the bigoted peoples of Northern Ireland were. The soldiers weren't to blame for the deaths in Northern Ireland, the terrorists on both sides were.
"The soldiers weren't to blame", cannot absolve the UK government and their deployment of their military operation in support of such a bigoted and unfair system.
Don't forget this was a problem that was there since partition and was allowed to fester. Conservative and Unionist party says all you need to know about UK policy in Norther Ireland since 1922.
The ordinary foot soldier must have wondered what in hell have I landed in. Hard to blame anyone in those circumstances but there was many a dark art going on in the Military hierarchy, you can be sure.
