Popeye's sailing out in the Pacific, spoiling for a fight with the Japanese. He comes across what looks a Japanese fishing boat, but, just before Popeye lets loose with the old fists, the Japs offer him a peace treaty. Popeye's all for peace, but are the Japanese men of their word? Written by Jonathan D. H. Parshall <parshall@citcom.net>

One of the few of the Popeye cartoons.
6 February 2007 | by (United States) – See all my reviews

Like "Spinach for Britain" only this time we find our favorite sailor, on lookout for any Japanese enemy ships that come by.

At first Popeye thinks they're planning on giving out peace. But soon finds out that they're messing with him. And soon it becomes a battle on board a Japanese ship.

This and many other WW2 titles don't see the light of day, due to it having the Japanese drawn in a stereotype way. The title & song itself says it all, that it's meant to be an insult to the Japanese(as they were the enemy back then).

Along with "Tokio Jokio" and a hand full of Snafu cartoons. This one's very misunderstood for it's theme. Not saying it's great in any level, just it's an example of how people were thinking during that era.

Where can you see it? Good luck finding it on the internet. I advise those who are Japanese to not view it. As I noted earlier, that it's very insulting.
