Canada is too intertwined with the US to truly divorce the US or even shift significant trade to Europe.
Australia can sell raw materials anywhere but the Red Sea being closed makes it take longer and be more expensive and who is really going to demand raw materials in Europe when the energy crunch hits? And we're bouldering towards that energy crunch (both natural gas and diesel). One of Australia's biggest competitive advantages in selling raw materials to China has always been relative proximity. Lower shipping times and costs.
Yes, the US has used Israel as a weapon in the Middle East (since ~1967) but what kept Gulf powers in line was the supply of weapons (to prop up unpopular regimes) and the free flow of trade. This war has shown that the US cannot defend its own bases in the Gulf let alone any of its client states (sorry, "allies").
I believe there's a nonzero chance the Israeli state collapses within the next decade. That's how much things are shifting and what a blunder this has been.
The GCC countries are going to have the redefine a new regional security architecture that includes Iran. That's inevitable at this point. If the US had been smart they simply would've admitted defeat ~5 months ago but they can't. Because of Israel. For now.
So Iran is America's Afghanistan (USSR era). The quagmire of Afghanistan was a huge factor in the collapse and breakup of the USSR. This isn't like Vietnam, which we could simply walk away from. Iran won and the Israeli state in its current form is doomed.
