And we almost invaded Syria because of this?

More significantly, however, the four-page "Government Assessment” of the case against the Syrian government contained not a single piece of evidence that could be checked independently. It was filled with “we assess” this and “we assess” that. To this day, the Obama administration has not released a shred of evidence that could be examined and evaluated.

Instead, the propaganda approach has been the old tactic of repeating an unproven assertion again and again, knowing that if a charge is declared with sufficient certitude often enough, the weak-minded will simply begin treating it as accepted wisdom. That’s especially easy when the target of the accusations has been thoroughly demonized as is the case with Syrian President Bashar al-Assad.
