The only way you can do that decrease taxes, balance the budget, and increase military spending is with mirrors, and thats what it would take.

Summary

This quote sarcastically suggests that it is impossible to achieve the goals of decreasing taxes, balancing the budget, and increasing military spending simultaneously. The phrase "with mirrors" implies that employing deceptive tactics or illusions would be the only way to achieve such a conflicting set of objectives. In essence, it points out the difficulty, if not the impossibility, of pursuing these goals concurrently due to their contradictory nature and potential impact on national finances.
