Unfortunately, buddy, you're a bullsh*t artist:
1. The crap the Iranians fired against Israel went full-range and would have hit had it not been intercepted - and it was all made by the Iranians, not the Chinese. It all would have gone full range to Israel, a distance of 900Km - that illustrates how far Iran has come and demonstrates how dangerous they are now.
2. The Israeli-made antimissile defense systems were designed and made by the Israelis, not us. Our antiballistic missile defense stuff wasn't available to them and doesn't have a very promising test record so far.
All you are showing is your extremely limited understanding of military technologies and your internal biases.
So something that gets shot down is successful? Ok. Retard.
