I see..."riddled with doubts" is the same as ordering them grounded.In this instance, it is.
They were presented with a system that they refused to deploy.
They refused to deploy it because they were "riddled with doubts" about it.
The action is refusing to deploy the drones.
The reason for the action is they were riddled with doubts.
I say that Bush took a specific action.
You are focusing on the reason why he took that specific action and trying to claim the reason is the action.
Bzzzzzt! You're wrong again!
