Explain the concept of terrorism and definition of terrorism

1) Assess the criticisms made by Judge Posner of the idea of creating a national director of intelligence. Do you think these are valid criticisms?
2) The caption of 18 U.S.C. 2332b refers to “acts of terrorism transcending national boundaries.” Does any other language in 2332b define “acts of terrorism?” Examine the substantive provisions of the section very carefully. Is there any place in the statue where the concept of terrorism or one of the definitions of terrorism is inserted in or is part of a provision describing a substantive violation of this section?
3) Is there an express definition of terrorism in 18 U.S.C. 2339C? If not, what definition of terrorism and theory(ies) of international criminal jurisdiction underlie the section?
