My statement was to show the absurdity of this fear that German troops training in Australia would somehow upset China. Not that the E7's in Germany will start carpet bombing runs Beijing. The E7 has no weapons.
Its not being based in Germany to annoy China, its being based there because NATO has a lack of high tempo AEW assets to cover its own immediate airspace. Because America over estimated its ability to build a mostly spaced based network to do this job, which resulted in the Americans not pushing ahead with a flying AEW program, and NATO, completely dependent on the US, bar its own small fleet, which had completely copied and is locked into the same death spiral as the US, also has degraded capabilities.
The only NATO member who invested in AEW in a considerable way was Turkey, who feels the least in NATO, and probably doesn't get much E3 time from the NATO fleet. So they bought E7's. Then when the Ukraine war started and Ukraine and the west needed levels of AEW coverage, they quickly became dependent on Turkey for that capability, which also Turkey has need of herself.
As apposed to China striking Australia which requires it to neutralize/over fly/sail past, Japan, South Korea, the United States, Vietnam, Singapore, Indonesia, India. Or conversely German troops in Australia to swim, 8,000km to China.
German troops in Germany are as much a threat to China as German troops in Australia. There is no closer movement to China by having them exercise in Australia. Any fear shows falling for Chinese propaganda and misinformation.
Which gets to the heart of the NATO mindset. Australia doesn't need to join NATO for protection from China or Russia. Australia is not in a precarious position, arguably less precarious than Europe is.
But there is this mindset that Australia is "not in the club". Australia is more active in NATO activities than many NATO members are.
Australia and Germany should have a "Status of Forces" Agreement, with each other. This would better able to facilitate large scale deployments and exchanges. I know this is a bit of a touchy issue, but Australia recently completed an agreement with Japan that the British later copied, and I think Germany will find Australia much easier to deal with in that regard.
Being able to do things directly with each other, without three services and thousands of Americans facilitating everything would be again hugely beneficial. We could embed people in each others programs, in each others forces, share knowledge, develop expertise, provide joint and cohesive feedback to defence industry etc.
The Wedgetail deployment is mostly driven by a lack of US capacity, and the US are well into their E7 program. But it may be an opening, to kick off a wider relationship. Australia has been trying for a while to build something with Germany. Ukraine is a case study where it makes sense to collaborate directly with each other, boxer is another.
Small steps.
