If you genuinely think these two events will shake the foundations of the US economy, then no investment is really going to protect you; you can't expect a system to shield you from the very thing that's breaking it.

There is crypto but even that got infiltrated by institutional wall street money. There are off-shore jurisdictions but the recent Iran war has showed these can be very vulnerable at a moment notice. There is China, but a Taiwan invasion could reduce your assets there to zero.

Honestly, I think the best bet is crypto/Bitcoin, by far. It operates across borders and still relatively insulated from government reach. Unlike gold, oil, or anything physical, it can be moved without physical visibility.
