Q: What do you do if you're a hacker with a sense of ethics and a burning desire to stop polluting countries who aren't willing to toe even the Copenhagen line?  What if that country was big, armed, and everyone else was just a bit afraid to tackle it?

A: Imagine if you will, a small group infiltrating the launch control systems of every other major power on earth, inputting a very specific co-ordinate, and setting a synchronised timer . . .

HUH: Well, the problem of bringing recalcitrant superpowers into line is that no single other superpower will ever be the first to fire, because they'll just make a target of themselves right away.  It's difficult to get your fellow superpowers to conspire with you to sync-launch, and even if you do negotiate there's always the chance that you'll all set up a plan, the moment comes, you launch your missiles - and no-one else does...

A small cadre of infiltrators would have no such qualms, and every missile would launch as planned.  The superpower being targeted would have to conclude that ALL those countries couldn't possibly have organised sex in Bangkok with a fistful of fifties let alone such a secretive and co-ordinated strike, so none of them are responsible, and besides, retribution on 75% of the rest of the world is a bit of a tough battle to take on, even for a superpower.

A message would have been delivered.

Think this is far-fetched?  Don't forget that almost every political advance in the world has been made, not by politicians sitting behind polished desks with secure jobs, but from people who realise that their fate is in their own hands and they need to act if they are to survive.  And the only difference between political monsters and political heroes is the direction the public takes on hearing the news...

Stay tuned to the news channels because as I so often say, if I can think of it now, someone's already thought of it in the past, and someone else has either already made it happen or is in the process of making it happen.
