Nuclear threats can lead to different responses like backing down, no impact, or retaliation. A study looked at how people in the US and Germany react to threats from Russia and China. They found that most of the time, nuclear threats don't really change people's opinions. But sometimes, threats can make people more afraid of a crisis or even make them more likely to support retaliation. For example, when Russia threatened to use nuclear weapons, it made Germans less supportive of strong responses to aggression. So, nuclear threats can have different effects depending on what is said and the situation.
