He is technically wondering how long until the first strike hits the US. He is highlighting the risk that the use of drones can get out of control. Sorry, but he is implying that the fact that currently so many innocent civilians are being killed is not as worrisome. That's what I read: "look what horrible things could happen in the future". It could be that he is not really implying that, but this is what I read, and I think that this is an extremely widespread opinion, specially among american citizens. If he is not implying that, sorry but I need a disclaimer. That's what disclaimers are for: to clarify formulations which are not obvious.
