getting back to the original topic (despite some people's best efforts to start in a flame war with me)

Why does Yemen need SCUDs?
a SCUD is a medium to short range ballistic missile, which means it has rather poor accuracy (better than V-2, and early US/Soviet attempts, but still crappy).
It is designed to be tipped with a tactical nuke for use against attacking or defending ground units. Mind you with a nuke it doesn't matter if you miss your mark by half a mile will still kill the guys at the objective. But Yemen has no nukes (as far as we know that is...).

same with Iraq.

interesting is it not?
