What are "realism" and "liberalism"?
Realism and lieralism are the two major theories of international relations. Realism is the theory that states only act in their own best interests, regardless of impact on other states. In other words, the state's primary interest is self preservation. Liberalism is the theory that gloablization has made states interdependent such that it is no longer in a state's interest to consider only its own self interests. Rather, liberalism believes that international cooperation is in a state's best interest.
When do you use the word "lie" versus "lay"?
"Lay" requires a direct object, and "lie" does not. For example, you "lay the pen on the desk" ("the pen" is the direct object) and you "lie down on the bed" (no direct object). However, "lay" is also the past tense of "lie". For example, "today I lie down on the bed" (present tense), and "yesterday I lay down on the bed" (past tense).
