Post-Cold War NATO has attempted to re-legitimize war as a method of advancing geopolitical objectives. Nations whose constitutions explicitly prohibit the practice - NATO members Germany and Italy, NATO partner Japan - have troops and other military personnel serving under the Atlantic Alliance in Afghanistan. So do NATO partners Finland, which had not engaged in combat operations since the Second World War, and Sweden, which had not done so in two centuries.
But according to Defence Secretary Hammond nations like Germany are not sufficiently involved in the wars of the 20th century and must play an even more pronounced role in them, present and to come.
There is no "quite a long while ago" when it comes to wars of aggression. There is only "never."
