This is a polite way of saying what Robert Gates, the previous defence secretary said more baldly, that having seen the paltry defence efforts that Europe is willing to make, its time for the US to drawdown.
The rest can usually either be used to buy an annuity (an income for life that will depend on your age, the value of your pension fund, and annuity rates payable at the time) or to provide an income via what is known as 'drawdown'.
Having authorised sending an additional 30, 000 troops to Afghanistan in late 2009, after prolonged agonising, Mr Obama always intended that a limited drawdown would begin after this year's fighting season, with more coming home in good time for his bid to be re-elected in 2012.
