NATO needs a complete rethink as to role, purpose and who does what, especially in light of the on going reductions and budgetary constraints on the armed forces since 1989. Something which we in the cadet forces are well aware. America is reducing its European footprint and you get a sense that not many other European countries want to or can fill the void. We can't, but you get a sense that the Armed Forces like it as it gives promotion chances / posts for personnel, other than that.
NATO served a purpose, although it didn't have to flex, during the Cold War as we knew where the lines were drawn, but since 1989 what exactly has been its purpose, where exactly is the threat, where are/is the line(s)?
As said when you look at the membership now it's like the EU absorbing the lost and dispossessed across the continent and beyond and the bigger it gets the looser its focus becomes, and like the EU it becomes a talking to get agreement rather than a doing organisation.
