It's weird take. Why wouldn't restaurants be accessible? There always were food-serving places, for all income levels. It doesn't really matter if you call them restaurants, pubs, cafeterias, guest house etc.

The change after WW2 wasn't really related to restaurants, but to the general increase of prosperity, when even middle class people suddenly had surplus income.

Well, even today, armed helicopters are... questionable. They are great against inferior enemy, but in open conflicts, they are just giant slow target waiting to be shot down. Their main selling point is the ability to hover over battleground, which is simply not possible if the enemy has proper AA weapons.

The assasination of Reinhard Heydrich, the only high ranking Nazi who got killed during the war.

There's plenty of documents about it, secondary effects and even some controversy (was it worth it?).

Were there "last minute attacks" at the end of WW1, as seen in the new "All quiet on Western front", or was it just dramatic ending for the movie?

Or in any other war, how common was attacking after the peace was signed, but not yet in effect?
