Depending on political discourse, the politicians try to win the favorite response from the audience. For this reason, the theory of critical discourse analysis (CDA) which is used to analyze political discourse forms the base for analyzing the data (Bush's and Al-Assad's first inaugural speeches). Systematic Functional Linguistics is used as an approach of CDA to analyze the data focusing on the point of transitivity and modality by which it is possible to know the way by which language serves to achieve specific ideologies and power.
