They don't want anything FROM us. They simply want to DESTROY Western Civilization. Nuke a port or two and global trade shuts down for years resulting in depression unlike anything ever seen before. Unemployment at 25% or more. Closed borders. Mass deportations. As Franks says, the loss of the America we know and love. It's pretty ugly to contemplate.
But this will never happen. America is strong...there will be major setbacks no doubt, but are not losing to these scumbags...we love our freedom too much.
Think smaller - and more economically devastating: forget the nukes and look at Britain 2 years ago. Hoof'n'mouth disease literally KILLED their markets and forced mass exterminations of healthy animals on the chance they they COULD have been infected.
H'n'M isn't fatal to humans, but humans can be (physical) carriers: Britain, many years without the disease, suddenly had it spring-up in various places pretty much simultaneously. Could the country have been a test case by terrorists? One could assume they have stocks of pretty much any virus/disease there is.
Imagine the same scale of H'n'M in the United States: kiss the beef industry goodbye. And the pork industry. Dairy industry. Wool. Horses. Not to mention field and building sterilization. What meat-animals are there that AREN'T affected by H'n'M?
And all this could technically be accomplished with a single loss of human life - so it'd DEFINITELY fly-below the DumAsCrap's radar. I'm not trying to be a tin-foil-hat-type here, but Britain never DID successfully explain how their (supposed) single animal imported into the country (the story I heard) got around so much to so many places in so short a time - compared to a bunch of people 'seeding' the animals and their fields from along the roadside.
