Q. If an object isn't moving, no external force acts on it. 

No it is always not true, there would be balanced forces which cancel each other out leaving no net force. Example: Sitting on a chair, the chair pushes up on you while gravity pulls you down, but you aren't going anywhere because those forces cancel each oyher and net force is equal to zero.
