Iran has launched satellites. Iran also has ASBM capability, which only one other nation has developed so far (China). Their rocketry technology is pretty good, overall.
If HAMAS had Iranian missiles, then why is it that these are never seen in use? Instead, there are silly little rockets (apparently made from plumbing parts) that despite the Israeli government reports stating that thousands are launched, seem to be spectacularly ineffective at killing percentage wise. Tens of thousands launched and only a few tens of people actually killed by these things? More Israelis die from domestic accidents with electrical appliances and allergies to peanuts.
I haven't seen a link that supports this claim, and it still remains peculiar that if it were true, then is it that the people in Gaza are only using tiny little rockets which hardly hurt more people in Israel each than peanut allergies do.
