Pretty pointless trying to sub-divide contributions in joint operations. The French are leading in Mali with UK and other support, the UK leads in other areas with allied support
remember that the UK was dependent for several years on NATO to provide marine recce - which a lot of people (including me) found unbelievable for a maritime nation.
That's the point of alliances - and we shouldn't resort to simple nationalistic point scoring if we want them to continue.
The alternative is a vast increase in spending (which won't happen) or a big cut in what we can do (which I think would be unwise)
