I think Putin & Corbyn would have loved it.
For me, it presented a case that we have become a shadow of our former self, militarily, politically and diplomatically. It seemed to show we only have a definitive capability against ill trained local militia type forces and lack the numbers to do any serious damage when faced with a numerically superior foe. It highlighted the likely divisions and political posturing within NATO that would undoubtedly undermine its capability as well as within our own ranks.
Quite thought provoking, but for all the wrong reasons from the perspective of a current serviceman. We mortgaged our entire military for 2 COIN campaigns, did neither particularly well, and are now stuck in a culdesac that also seems to be a one way street.
