"The British government has learned that Saddam Hussein recently sought significant quantities of uranium from Africa."
These 16 words were the pretext for the disastrous US war against Iraq. These words were false and US officials knew they were false when they were uttered.
But at least after the fact we can examine the evidence and know that our leaders used yet another false pretext to lead us to catastrophe.
How will we ever determine if a presumed cyber attack (a) actually occurred, (b) was dangerous enough to justify a response, or (c) could have been dealt with in some way other than blowing up people?
Seems like the perfect pretext for another catastrophe.
