I personally prefer a higher equity allocation than Vanguard's, but if they're wrong they can be sued. Their information has to be reliable, or they'll be sued. Not true of most people's information, which is why I put Vanguard's allocation before mentioning my own.
Before 2020, I liked an even split between US equity, international equity, and bonds. Rebalancing was easy: make all 3 match. So there's Vanguard (46% equities), traditional retirement advice (60% equities), and the approach I took (67% equities).
20% Bonds
2% cash
78% international shares.
Allocating 0% US equities is extreme. Take Vanguard Total World ETF (VT), which has 61% allocated to North America. U.S. stock market capitalization is larger than the rest of the world combined. I'd suggest setting aside your reasons for 0% U.S. equities, and allocate a chunk for the diversification benefit.
