US "defense" policy dictates that the president must always be able to launch nuclear weapons in minutes. 1,770 weapons are maintained ready to fire on command. The tools for the president to order nuclear attack are contained in a suitcase nicknamed the #NuclearFootball and is never more than 100m away.
Here is the Nuclear Football entering the #Hiroshima Memorial Peace Park with Biden during the #G7 yesterday (Chugoku Newspaper Press image).
It is callous to bring the ability to launch nuclear attacks from the place where more than 100,000 were killed by a previous US nuclear attack. It is also the reality of nuclear weapons for the G7, rather than the performance of wanting a world free of nuclear weapons. The reality is a world were the use of nuclear weapons is never more than 100m away.
