From Glenn Greenwald:

But when these weapons are wielded by Western governments, the precise opposite framework is imposed: describing them as despotic is no longer obligatory but virtually prohibited. That tyranny exists only in Western adversaries but never in the West itself is treated as a permanent axiom of international affairs, as if Western democracies are divinely shielded from the temptations of genuine repression. Indeed, to suggest that a Western democracy has descended to the same level of authoritarian repression as the West’s official enemies is to assert a proposition deemed intrinsically absurd or even vaguely treasonous.
