(c) For the purpose of this section "foreign government", "foreign official", "internationally protected person", "international organization", "national of the United States", and "official guest" shall have the same meanings as those provided in section 1116(b) of this title.
Punishment provision was rewritten to make it more definite by substituting a maximum of $5,000 in lieu of the words "fined at the discretion of the court." As thus revised this provision conforms with the first punishment provision of section 111 of this title. So, also, the greater punishment provided by the second paragraph of section 111 was added to this section for offenses involving the use of dangerous weapons.
