In some fanfics, characters from other universes might initially be in awe of the Fuhrer due to his power and status. They could approach him with caution, trying to figure out if he's an ally or a threat. For example, a character from a magical universe might be intrigued by the alchemical powers in the Fullmetal Alchemist world and see the Fuhrer as a key to understanding it all.
Bradley Manning was a U.S. Army soldier. He leaked a large amount of classified information to WikiLeaks. This act was seen as a major event in terms of government transparency and national security.

Well, 'A Christmas Story' features its own set of actors, and Bradley Cooper has no part in it. This movie has its own charm with different actors portraying the various characters related to the Christmas - themed story, but Cooper isn't among them.

I'm not very familiar with this specific visual novel. It might be a rather unique and perhaps controversial one given the combination of words in the title. It could be a parody that takes historical or cultural references and twists them in a fictional and satirical way within the context of a visual novel.
It might be significant in terms of design influence. Maybe the Bradley watch had a unique aesthetic that inspired other watchmakers. For example, its shape, color scheme, or the layout of the dials could have started a new trend in the watch industry.
