Are you making a lasting transition to heavier exUS emphasis, and if so, how?

I've been primarily an investor in VTI for about 15 years now, and have always wondered whether I should be more heavily invested globally in the interest of diversification and hedging against a protracted downturn in US stock returns. For reasons that should be plain to all, these past few years have me considering rebalancing completely away from VTI and into VT. However, there's no getting around the fact that owning VT does inherently mean you own a lot of junk (same with VTI, really).

Are you in the boat of making a transition over to a global emphasis as an investor, and if so, how are you approaching it? Have you built a portfolio with a greater emphasis on certain regions? What percentages are you allocating?

Thanks.
