Thoughts on Redistribution Based on World Events

Hello fellow investors, I have long been an investor in XEQT and VFV with no regrets. Considering what has been happening recently down south, and looking at the high geopolitical tensions, I am worried about the potential of the US economy collapsing as we know it. This could be due to new conflicts, civil unrest/war, fall of NATO, etc. Based on this, I am reconsidering my investment strategy to be more diversified whilst putting much fewer eggs in the US economy. This is what I am thinking: - ZCN for domestic exposure in Canada (20%-30%) - ZEA for non-NA developed markets (10%-20%) - ZEM for emerging markets (30%-40%) - ZSP for US only (like VFV but by BMO) (10%-20%) Reason for higher focus on ZEM is because if what I'm saying is true, ZEM would probably see higher returns. I understand that might seem like a knee-jerk reaction, or fear investing, but what I'm considering is mainly more diversification... I'm not betting completely against the US as per ZSP above. If it helps, this all would be in a TFSA for long term investing (15-20 years). Would love to hear your thoughts on this and how you would distribute what I have above. Am I crazy? Should I just stick with XEQT?
