First, postmodernists believe that language plays a vital role in constructing reality and the social world.  Campbell said，there is nothing outside of discourse, we can only get sense of reality discursively. The postmodernists reject the idea that objective reality exists independently of language, arguing that our understanding of the world is always mediated through language and interpretation. The focus here is on the linguistic production of discourses—they not only carry meaning, but also create or construct social reality。
Language is not simply a neutral tool for communication, but rather shapes our perception of the world. Postmodernists emphasize that language is not a transparent medium for conveying objective truth, but rather a system of signs and symbols that are subject to interpretation and manipulation. Different interpretations of language can lead to multiple realities and perspectives.They believe that language and our interpretive traditions shape our understanding of the world. Language shapes our thoughts, beliefs, and behavior, it can be taken as a mean of social control, as certain discourses and linguistic practices can marginalize and exclude certain groups. At the same time，Language is seen as a social construct that reflects and reinforces power dynamics and social hierarchies. It is through language that dominant ideologies and narratives are established and maintained. Discourse shapes power dynamics in the following ways：
-Discourse constructs and reinforces social norms, values, and ideologies, which in turn shape power dynamics within a society. 
-Language is a tool of power, as those who control dominant discourses can shape public opinion, influence decision-making processes, and maintain their position of authority. 
-Discourse can marginalize and exclude certain groups by perpetuating stereotypes, stigmatizing language, and reinforcing social hierarchies.Power is exercised through the control of language and the ability to define and shape the meaning of words and concepts.
-Discourse can create and maintain power differentials by privileging certain voices and perspectives while silencing or delegitimizing others. 
-Challenging and deconstructing dominant discourses can disrupt power dynamics and create space for marginalized voices to be heard。
The use of language in international relations and foreign policy can shape the identity and actions of nations and influence perceptions of threats and dangers. Language can be used to curb contingency and domesticate challenges to dominant identities, thereby enhancing a particular understanding of safety and danger.

Language plays a crucial role in shaping collective identity by providing a framework for interpretation and meaning. Discourse and language construct and reinforce power dynamics and hierarchies within societies, influencing the formation of collective identities.
Using language to define boundaries and distinguish "inside" from "outside" helps build collective identity. Language is not a neutral tool, but is influenced by social relations and power structures that shape the perception and manifestation of collective identity. Delineation of boundaries and representation of identity composition through language contribute to the formation and maintenance of collective identity

Benefits of deconstructing political discourse:
Deconstruction is a theoretical framework developed by philosopher Jacques Derrida that challenges traditional concepts of language, meaning, and truth。 Deconstruction is because the text has no fixed meaning, we need to reveal the relationship between the text and the meaning. Its purpose is to reveal the contradictions and binary oppositions inherent in texts and discourses, and to reveal the instability and complexity of language. Deconstruction emphasizes that meaning is neither fixed nor objective but is constructed through language and interpretation. The aim is to diffuse and destabilize dominant discourses by exposing the underlying power dynamics and hierarchies that shape them. The purpose of deconstruction is to examine the language and assumptions embedded in the text that challenge and undermine established norms and ideologies. Deconstruction also emphasizes the role of language in establishing and maintaining power structures, arguing that language reflects and reinforces existing power relations. By deconstructing language, she aims to reveal and question these power dynamics.
-Revealing power dynamics: Deconstructing political discourse enables us to identify and analyze the power dynamics embedded in language and speech. It helps to reveal how certain discourses reinforce existing power structures and marginalize certain groups.
-Challenge the Dominant Narrative: Deconstruction enables us to question and challenge the dominant narratives and ideologies that shape political discourse. By critically examining the language and symbols used, we can expose hidden biases and assumptions, opening up space for other perspectives. It allows for a critical analysis of the language and rhetoric used by political actors, revealing manipulative tactics and hidden agendas。It questions the "truth system" that operates unquestioned in society and challenges the dominant narrative that serves the interests of elite actors
-Promoting inclusion and diversity: Deconstructing political discourse helps create a more inclusive and diverse public sphere. By eliminating oppressive speech, marginalized voices can be amplified, and their experiences and perspectives can be recognized and valued. By deconstructing political discourse, alternative perspectives and marginalized voices can be brought to the forefront.
- Enhance critical thinking: Deconstruction encourages critical thinking skills by questioning fundamental assumptions and meanings in political discourse. It promotes a more nuanced understanding of complex issues and encourages individuals to think beyond the surface narrative.
- Promoting democratic participation: Deconstructing political discourse can promote active citizenship and democratic participation. By analyzing the language and rhetoric used by politicians and decision makers, individuals can make more informed decisions, hold power holders accountable, and actively participate in the formation of the political process。

Overall, postmodernists argue that language is a powerful tool in shaping our understanding of reality, and by critically examining and deconstructing language, we can uncover hidden biases, challenge dominant narratives, and promote a more inclusive and diverse society
