no need for specific evidence

"Prince Torki explained that Saudi Arabia also believes

that Iran is playing an unhelpful role in Yemen.  Dismissing 
the need for specific evidence, he said it was hard to 
explain how the Houthis, as a poor tribal group, managed to 
get so much money so quickly to obtain the heavy armaments 
that they have been using absent the help of some outside 
group.  It is also hard, he argued, to explain the striking 
similarities with techniques that have been used by 
pro-Iranian groups in Iraq."
