The Answer:
1. Drop Welfare
2. put people to work at Slave Wages.
3. Restart Draft.
4. Rally people and Rebuild Navy.
5. Invade weakest Neighbor—like some Island Nations in Pacific. How about North Korea?
6. Hold lots of Parades, build shrines, make people proud and able warriors. Control Press, take apart internet, put in a secret police. Works every time!
Too late for all of this.
As for slave wage you won’t ever institute it slavish enough to compete with Red China on cheap labor.
And whom are you about to draft? Japanese polls shows their teenagers aren’t manly enough to have sex with girls. Their ideas on firearms and warfare are coming from Call of Duty.
