I have a few ideas.
1- Closing some of the 1000 bases they have.
2- Ending their interventions (read: 21st century colonial wars) in all 7 countries and retiring counter-insurgency (read: anti-resistance) equipment.
3- Ending their clandestine drone strikes and special forces operations in multiple small countries and retiring the then surplus equipment and people.
4- Somehow convincing the senators to allow procurement based on engineering and manufacturing constraints, and military needs instead of politics.
5- Stopping sending the CBG's to patrol (read: participate in provocations) in distant waters.
I guess these would help.
