Coward Albo won't send Naval Help, page-66

The US didn't request Australia to join a war, they requested we help protect international shipping routes after attacks have been launched on freight ships in the area.

The US isn't actively involved in the conflict, their and other western countries presence in the area though would not only protect freight and innocent lives on those ships but it would also help dissuade other countries getting involved and possibly expanding the conflict.

We should be part of the US operation to safeguard shipping routes
