Almost, but not quite. The difference would be that the US isn't killing civilians just for the sake of killing civilians to cause terror.
The USA wont kill everyone that opposes them with such a campaign, but the point is the same as "terrorism", to send a message of fear if you dare oppose us, or associate with people who oppose us, damn the "collateral damage".
Make no bones about it, this is exactly the same kind of asymmetrical warfare that the USA itself condemns as terrorism.
