Well the crap the Chinese sold the Iranians had a 99% failure rate against the crap we sold to the Israelis.
Our military always underperforms at international displays, so they can ask congress for more money.
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.
