Go back to 2008 spending levels, then cut 25% off the top & across the board (if not more).
Every discretionary program could be cut in half and it still wouldn’t balance the budget against the entitlements.
Without reform to entitlements there is no hope of balancing the budget let alone whittling away at the national debt.
You could eliminate the military spending almost THREE TIMES and just equal the deficit.
We don’t have THREE military budgets to cut.
