Fixed, Adam. You'd unselected "html" (the little radio button at the bottom of the post box), which made the whole thing display as text instead of a link. For future reference, you can just hit the "edit" link in the top right corner of the post to fix it.
I've been going through my archived files to try to find the story (from the Melbourne Age, I believe) of the Iraqi farmers convinced that British forces had loosed giant moles on the unsuspecting public around the outskirts of Basra. And a previous story (source unknown, but probably the same esteemed publication) of several ducks that had been arrested for Spying.
That actually seems like the sort of thing that could work today. Get a bunch of sleeper agents with citzenship in your desired country, so that their pets don't need to go through quarantine, then have them come back to your country, infect the animals, then go back home and release them. The disease will be shielded from detection since it's being carried on the cat/dog/whatever, so the only way I can see for the country to figure out what's going on would be the sudden increase in people travelling to country X with pets.
Meh. It'd work better today using people as the disease carriers. They only had to use animals back then because in an ethnic society its hard to sneak enemy agents in. Today, in our multicultural society, just get a bunch of people with resistant TB or malaria and shuttle em into a major city. Joy happy fun time.
