Here's the problem we have. By most accounts the only reason the green light hasn't been given to Ukraine for wider use of the Storm Shadow missile (UK weapon) in their defense against Russia, is because of a US veto. A veto they apparrently only have due to a single component for the weapon coming from the US.
If this is the case, and the US is using their military technology supply chain as leverage with its allies in this way, then Keating is right, and Australians should be concerned about a critical arm of our defense structure being open to that risk.
There is however other possibilities, such as, UK wishing to talk the talk, but not walk the walk on wider military support. In other words essentially agreeing with the US about the risks of escalation, but wanting to be quiet about that fact.
