"One day Europeans may find that the US military is not there to deal with threats lapping at their frontiers."
In the 1970s, Mogens Glistrup, a prominent Danish politician, became famous for suggesting that his country replace its armed forces with a recorded message saying "we surrender" in Russian.
Glistrup is no longer with us but his approach to defence seems to be gaining ground. Europe's ability to use military force is dwindling fast, and with it the power of Europeans to defend their interests around the world. It is true that there are many troops from European countries deployed in Afghanistan, and the French are in Mali. But, behind the headlines, military capacity is shrinking.
