Much as I hate them, the only way of success in something like this is to court the press into whipping up a frenzy of public support.
The UKNDA look to be a singularly unimpressive lot. I know there aren't serving officers in there for good reason, but the retired lot of 'front line' advisors are hardly world beaters. It looks Navy centric (read the mission statement first line) has no RAF players with any track record and Bob Stewart is the only army guy with a profile and a good reputation. Take away the 'patrons' who are clearly letterhead names, then you don't have a lot of clout left. As for the security advisor, Professor Medhurst, didn't we just jail a Flt Lt for being a walt....Read into this guys CV and his credibility collapses-full professor you must be having a laugh!
A real life Jack Ryan!
So, good luck all, 100% behind you with the ideas, just think the reality will be very difficult to achieve.
