Why should I respond to your assumptions?
As it happens, I do agree ... mostly ... with the statement. I don't agree completely, however. The purpose of the military is to be capable of killing people and breaking things, if necessary.
If the only purpose was literally to kill people and break things, we'd always be at war, n'est pas?
I think it is understood that they will kill people and break things when necessary and does not need to be explicitly spelled out.
