A good defense is not neglecting your offensive capabilities.
Frankly slotting into a large allied force benefits us more than covering our massive coast line in missiles and drones.
No doubt… But relying on subs, built by a criminally corrupt fascist state, who has already shown that they will abandon or turn on allies at any time, is the dumbest scenario to entertain.
Our agreements shouldn’t completely abandon the US, but they should be kept at arms length, and the possibility that the US could be the invading force should not be neglected.
Okay, so go with other subs. Don’t go with this stupid idea that we can defend our coastline with missiles and drones.
The subs aren’t for defending the Australian coastline they’re to contain China to the South China Sea.
Which is stupid anyway because it’s a very shallow sea and subs are ineffective there. But that’s the strategy chosen by the US.
I found this recent video by Puck Nielsen pretty enlightening.
