Often when I read about realism, I eventually come across someone telling the world that "realism is a dead theory" that the "world doesn't work that way anymore". Then, the same liberals will go on news shows and talk about how the U.S bombing in other countries "create terrorist"; that our foreign policy is "responsible for the instability". Which means they like realism, but only when it suits them. See, realism can be a tool for peace in that it provided us with real reason to deescalate situations instead of bombing; a reason to show restraint when we can invade. Analyzing our actions impact on others, by sort of putting ourselves in their heads, how they might react, even think, as a result of our action-- by doing so we can reduce a lot of the current harm done in the world by the real "Deep State".
