International trust is a perception about how people can trust other nations, it can also be an explanation for people¡¦s perception about the nature of international environment. The study shows that when people have higher levels of international trust, they are more optimistic about the nature of international environment¡Fon the contrary, people are more pessimistic about the nature of international environment. There are many variables that can influence international trust, and political trust is one of the most influential. Therefore, I try to analyze international trust and political trust in Taiwan through telephone interviews and intend to testify my hypotheses. Furthermore, I will make international trust a standard for people¡¦s attitude towards foreign aids in order to respond to revisionists¡¦ point of view. Thus, we can prove that people surely can form their own information shortcut and express their own feelings without the suggestion of political elites.
