Our reading
An editorial interpretation.
The speaker says stopping this man would put their job at risk, then jokes that his world-conquering ambitions depend on winning a government grant. Grand tyranny is paired with humdrum bureaucratic funding, and the deadpan exaggeration makes both the man and the speaker's reluctance sound absurd.
