What's the right word to describe an act of making a citizen of one country (by either paying him or, perhaps, setting him up in some way) start getting and sharing some important info about his own country?
For example,
The FBI forces finally ______________(ed) the Russian scientist Ivanov in 1957. So, starting from 1957 he's been sending all important information about Russian militaries to the White House.
(or something like that)
