And not a single fact to disprove the claim that it was 99% successful.

In contrast, Israel's response showed they could strike deep into Iran and that Iran's defences were near useless. And if you want to talk deterrence- unlike Israel's immediate neighbours and the Palestinians- Iran is a lovely distance away to drop a nuke on it if Israel, or to take out its oil fields and ports. Meanwhile, Iran showed it could injure a Bedouin Arab, in keeping with its disdain for Arabs and can shoot missiles towards Al Aqsa and other Holy places for Muslims. Yay Iran, so much winning.
