Japanese submarine raids on the US West Coast would harden American retaliation

How might Japanese commando raids launched from long-range submarines against the US West Coast affect the war?

They would likely intensify American anger and strengthen demands for severe retaliation rather than produce a useful Japanese strategic advantage.

Raids on the US West Coast would add to the shock already caused by Pearl Harbor. The likely result would be a much harsher American public and governmental response. No durable operational gain for Japan follows. The main consequence would be political escalation and stronger demands for retaliation.
