The US GDP for 2020 was $21 trillion.
With that, we spent < $800 billion on our military... or 4%
The US govt spending for 2020 was ~$6 trillion.
which would make military spending ~13%
in comparison, we spent ~70% of all US govt spending on entitlements
Social security and medicare that I paid into for over 50 years are not “entitlements”.
