There’s a former world leader who’s long been affiliated with an organization once labeled–by the United States, among other nations–as terrorist.
Remove the first three letters of his name, and the last three letters of his name. The remaining letters–the dead center of his name–will spell a word closely associated with terrorist groups.
Who is the world leader?
Edited to add: This was apparently a tough one. SMWinnie was the first to solve it…solution here.
