Scuds... or Fireworks

A Scud missile displayed in Raqqa, Syria, this week by ISIS is “more propaganda than operational” – meaning it is unlikely to pose a military threat, for some reasons that may be convenient to know, just to calm the non-israeli people that may be alarmed:

1. First of all, the missile need fuel (We will not say which one). ¿Do they have? If they do not have fuel, they have no Scud to throw. 
2. Second, the fuel tank of the missile must be filled. And it is not easy. ¿Do they know how to fill it? If they do not have the know-how and tooling to fill it, they have no Scud to throw.
3. Last, but not least, Scud missiles are not fireworks. ¿Do they know how to launch it? If they do not know how, they have no Scud to throw.

¿And what about israeli people? Israeli people has no reason to fear the Scud, as even if the Scud is launched towards Israel, it will never hit any populated place.
