>4% of the gdp though. So compared to the percent of gdp, it's a lot less than other countries.

3.3%ish. And most of the west relies on US logistics and intelligence.

Even as a European I would be happy for the US to spend less and the Europeans to build out more logistics capability. The UK is the only country with a reasonable airlift capacity. French operations in west Africa partially depend on that and the US.
