Well unfortunately, all anyone who still believes this has to do, is turn on the T.V. and watch the daily news.
Ask yourself why exactly, are the 'Iraqi army' now busy fighting for cities once held by the British.
Indeed, they are having to fight for the very ground that the British fought for, occupied and defended.
In fact, the very same ground, that is until they were withdrawn, whereby the Islamist extremists then simply returned and took it back for themselves.
Sadly therefore, with no gain whatsoever, the futile nature of their deaths has been both clearly and indeed quite shockingly, exposed.
Lamentable a loss it is, regrettably they did die in vain.
