SUBVENT: also means in an American dictionary, the Government coming to the
aid of.

Essentially you are correct, and he intends to write subvert. If he had used
SUBVENE there may have been a better sense, since it can have the meaning of
coming to the aid of, as preventive measure, as in the sense of to cause to
have relief.

It seems though he confused the transitive subvert with the intransitive
subvene.

SUBVENT: also, pls. see plumbers guide to underwater boats (1) and (2);
vent beneath the upper (vent) as in 'louvres' - thks..
