I recall the Spanish withdrawing their 3500 troops after the Madrid train bombings. They were replaced by 800 Royal Marines which struck me as a fair swop...
We must not expect our wonderful NATO allies (apart from those involved now) to help out in any way in the dangerous parts of Afghanistan. They've got some nice uniforms, though, don't you think?
That said, just imagine what an EU army would be like, particularly if it were "led" by the French.
