so lets get this straight, in your opinion, it's better for a state to fund a non state actor and direct them to do terrorist activities, than for the state to do it itself?
i.e. the terrorism should be condemned but the state sponsor of the terrorism has clean hands.
I'd argue just the opposite, the state sponsor of terrorism is actually worse than a state that takes action itself and doesn't delegate it to a 3rd party.
