I don't know how much we can trust these things, but I looked up what percent of the US economy is based on trade vs domestic activity, and we come in at 27% based on trade.
The other members of the G20 were way more:
United States: 27%
Germany: 100% (exports 50%, imports 50%)
France: 73%
United Kingdom: 70%
Italy: 81%
Canada: 67%
Japan: 46%
China: 38%
India: 49%
Brazil: 39%
Russia: 47% (pre-2022 sanctions; likely lower now)
Mexico: 85%
South Korea: 96%
Australia: 50%
Argentina: 33%
Turkey: 81%
Indonesia: 45%
Saudi Arabia: 61%
South Africa: 65%
European Union (aggregate): 96% (heavily trade-driven due to internal EU trade)
It seems to me that we are a MAJOR outlier in how trade is handled for us, and also it seems like we could be a lot more self-sufficient than the other members of the G20.
Am I interpreting this correctly in that it seems to me that we could survive a trade war much easier than they could because we are a lot less reliant on trade? Certainly not an expert on this so I'm asking, not telling.
