How can you tell Hezbollah's lying?

Not just when they move their lips, as the old saying goes, but pretty much any time they communicate in any fashion. There's been a lot written lately about terrorists feeding fake stories to western journalists, as well as faking and/or staging photographs and video. An Aussie paper reports on a humorous attempt at photofakery:

http://www.moqavemat.com - an Iran-based website run by the Hezbollah terrorist group - is running this picture (above) of what it claims is the Israeli ship it hit with a missile last month.

Now look at the Royal Australian Navy’s picture below - as published by Defence Industry Daily - of its sinking of the decommissioned Australian destroyer-escort HMAS Torrens off the coast of Western Australia in 1998 . We were told at the time the Torrens was deliberately sunk by a torpedo fired by one of our own submarines, the HMAS Farncomb.

Should we now think that we were in fact attacked by Hezbollah - or is this just the latest proof that Hezbollah will lie and lie again for propaganda gain?
