Focusing on the Indian Ocean does makes sense, now that you guess mention it especially if China has taken enough control of the South China Sea. Does it mean that the AUKUS coalition will leave Japan and Korea on their own?
Is that maybe why Japan has brought forward a more neutral prime minister candidate?
Once AUKUS can drop their Korea, Taiwan and Japan allies, they actually can effectively block the Malacca straight without hurting important East Asian allies. Because if AUKUS block the Malacca strait right now they will hurt Korea, Taiwan and Japan more so then they would hurt China given China's expanded trade routes with CPEC and BRI bypassing the Malacca strait.
If I were South Korea I would try find some deal with North Korea and ask Russia to expand the power of Siberia pipeline network into north and south Korea. Japan could see if they can fix ties with Russia for their energy needs might the Malacca strait ever be blocked.
AUSKUS represents a massive strategic retreat by the US from East Asia, as it becomes increasingly clear their forward positions there are now increasingly untenable in a shooting war.
SK and Japan almost certainly noped out of the proposal to form AUSKUS, which I’m certain was originally floated as an Asian NATO, and would have included both as not even Boris, Biden and Morrison are so oblivious as to not see how ridiculous their full pink AUSKUS club looks as the Asian NATO.
AUSKUS cannot and will not block Malacca as doing so will end world trade. That’s not the play.
The play is to pick the low hanging fruit of attacking Chinese flagged ships in the Indian Ocean while leaving all others alone. That way they don’t need to try to work out which neutral flagged ships are going where, and also can effectively deter neutral parties from using Chinese flagged ships, which will be the main source of economic pain rather than the few ships they do manage to seize and sink. But even that is just more annoyance than substance in the grand scheme of things, with the main damage to Chinese prestige. At the cost of fully dropping all pretence at being about rules and laws on the part of AUSKUS, so even that is a double edged sword.
