Nuclear subs with nuclear weapons are the best deterrence, so long as we remain neutral and non-aligned with other western partners who are looking to start conflicts.

Keep theses subs within our territorial waters so as not to escalate tensions, unless there is a heightened state of tension and conflict seems like it will be inevitable.

Focus on trade and nation building, not war.
If we play stupid games we risk winning stupid prizes.

Respect is a 2-way street.
You don't get it from others if you don't offer them likewise.

Not that it matters, these '15 minute cities' they plan in the future are Orwellian and hellish. Look it up.
There's nothing left to fight for anyway, our nation has been conquered.
I feel sorry for the future citizens of the world and and am sad with what we'll be leaving the future generations of Australia to endure.
