No combat experience myself, but I’ve had grandparents who fought in WWII and spoken to many WWII vets.
I’ve never once heard a WWII Veteran in this part of the world refer to the Germans as “Nazis”- it was always “Jerries”, “Krauts”, or “Germans”.
My dad used to be a reporter, and he went to a number of 50th Anniversary type deals in the early/mid '90s, where veterans from both sides re-visted places like Crete and Monte Cassino.
Dad said one of the fascinating things was talking to a group of German anti-tank gunners, who were recounting a story about the time they had set up their anti-tank gun to cover a road at Monte Cassino. They’re all having a cup of coffee when suddenly Englander Panzers showed up about 100m away, giving them a perfect broadside shot. Unfortunately, the officer with the key to the safety catch (or something similar) was off having a piss and by the time he got back four of the tanks were out of view, so they shot the fifth one then promptly relocated.
Half an hour later, dad was talking to some English tank crews, and a group of them were telling a story about how they were driving through some ruined village and suddenly realised they were in the middle of an intersection with a German anti-tank gun aimed right at them about 100m away… yet it didn’t shoot at them. Nor the next tank, nor the one after that, and when the fourth tank passed they were wondering what the hell was going on (they could see the German gun crew who were clearly trying to load the gun and bring it to bear), when the fifth tank suddenly blew up.
To cut a long story short, it turned out that these guys were the ones driving the tanks that the German gun crew he’d been speaking to earlier had spotted, but couldn’t shoot because Leutnant Hans had been off with his trousers down and his dick in his hand relieving himself against a wall. So, Dad gets them together and the Germans and the English vets were buying each other drinks, laughing, and reminiscing about the war together in no time at all.
Dad also said that he heard lots of stories about soldiers refusing to machine-gun tank crews escaping from burning tanks, not shooting soldiers because they saw they had a wedding ring or were carrying a wounded comrade, and also of both sides having shouted conversations with each other even as they were shooting at them.
I also knew a chap who’d been a Sunderland Flying Boat pilot during the war- he told me of the time they depth-charged a U-boat in the Atlantic somewhere, and saw it blow her tanks and surface. They circled overhead and saw the crew getting into liferafts, so they radioed the U-boat’s position to a nearby Royal Navy cruiser, which came and picked up the survivors. They waggled their wings at the Germans and left, on the theory that their quarrel was with the U-boat, not the crew. As the crew were going to be rescued and the U-boat was sunk, it was a good sortie all around and they certainly wouldn’t have to buy any drinks in the mess that night.
In short, it seems that most of the soldiers here respected the Germans as opponents- I’ve never come across anyone who said they hated the Germans- but there are rather a lot of people out there who won’t buy a Japanese car or appliance, as has already been mentioned.
