The definition that searching google gives is "the use of violence and intimidation in the pursuit of political aims", which drone attacks certainly fit into.
I think the point is that drone strikes (targeting angry people with guns and bombs) are meaningfully different than someone blowing themselves up in a a crowded market or mosque (targeting people whose religion is slightly different from his or her own).
You can say they're the same because they're "the use of violence and intimidation in the pursuit of political aims", but there's something of a different quality to those political aims that warrants a distinction.
