Would opposition within Japan prevent acceptance of Soviet parity?

The bargain could survive if enough influential Japanese groups valued three extra battleships and expected Soviet construction to remain slow.

Soviet parity would face opposition in Japan. The proposed bargain gives Japan three additional battleships within a treaty lasting only six more years. Japanese leaders could expect slow Soviet construction, so paper parity would not immediately produce an equal operational fleet. The forecast depends on enough influential Japanese groups valuing those gains to keep the agreement in place.
