Just what we need - being dragged into another stupid US conflict. One in ten crew members on US attack subs is Australian, according to the Royal Aus Navy - as part of training for the $368 billion AUKUS program.

I feel like people don't realize how rare and against norms this kind of unprovoked attack is. Only four ships have been attacked by subs since world war 2 in all the military engagements that have occured over that time. This act is a massive escalation of hostilities.

The Iranian frigate was unarmed (no missiles or anti-air arms), as it was returning home after a friendly military training exercise with India that required Iran's ship to follow "peace protocol". So also it's yet another US war crime. India is pissed about this too because their guests were murdered - they rushed rescue boats and helicopters to the site, but were too far away to be effective. Sri Lanka was closer and managed to rescue just 32 survivors of the 180+ crew in their rapid response.
