The thing which a government does when it vows to achieve disarmament is to:
Be accountable
Show the destruction of weapons to the world
SIgn peace treaties.
<h3>Disarmament</h3>
This refers to the situation where a country decides to reduce, limit or eradicate its military weapons, usually nuclear weapons.
With this in mind, when a government says that it wants to achieve disarmament, then it would have to go through the process of disarmament which has to be transparent and open to all and also a legal contract would be signed.
