Propaganda leaflet

Hello all,
I recently posted about my Good Luck flag on this forum and got fantastic responses, and I learned quite a bit of information. Now, I'm back with another piece of history that I have a question about. I have a propaganda leaflet that was dropped on Okinawa during the invasion in early 1945. It's a very neat piece of history! I was wondering what exactly it says. If anyone could translate it, that would be awesome! Also, I'd like to know if any else has seen anything like this before. I've searched the web looking for one like it to no avail. If anyone has any other bit of information about the leaflet besides what the translation is, that'd be wonderful as well! I have the pictures posted below, if you need a closer picture feel free to ask.

Thanks!

Is this long, drawn-out war worth it?

Google "Airborne Leaflet Propaganda" and you might find some good reading.
