It can be a little uncomfortable watching the wartime WB and MGM cartoons (e.g., in Avery's 'Blitz Wolf', where Japan is bombed in a 'funny' scene, a couple of years ahead of the real thing), and the frequently derogatory textual interjections or visual puns against the enemy can make you squirm a little - but is this all that different to the recent Danish cartoons which upset many Islamists? For this reason anyway, WB have not been exactly eager to have these cartoons thrust, unedited into the public view 60 years later, but luckily a lot of them have fallen into the public domain because someone forgot to renew their copyright, so (in Australia anyway) they can be found fairly readily if you do some digging.
Let's not pretend this is cartoon gold. In fact some of it doesn't make a lot of sense (I don't really understand the sequence with the phone booth), but Von Vulture and his underling Schultz are memorable and comic villains, and Daffy is appealing in his transitional phase - here he still retains his early penchant for going crazy and bouncing around the room going "whoo-hoo!", though to a lesser extent than in his earliest shorts.
Daffy parachutes in to make life a misery for Von Vulture, who has orders to stop any more commandos getting through the lines. After 6 minutes of general idiocy, Daffy ends up being fired in a giant cannon only to land next to a rotoscoped Hitler, which makes one of the most peculiar looking scenes I can think of in a WB cartoon.
I nearly gave this 3 stars. It's nice to see Daffy coming out on top for once, and Freleng/Maltese do a nice job of balancing wartime propaganda with artistic considerations.
Not a classic, but still fun, if you can see it as a period piece and get over the inevitable touchiness of wartime portrayals of the 'enemy'. Nearly 3 stars.
