> patriot is not effective against hypersonic, multiple vehicle missiles or decoys (which would require 1 patriot per vehicle) and is dependent on 2 radar systems functioning in the correct locations and the correct angle of attack from firing location

This is mostly accurate. Patriot is effective against every "hypersonic" it's been fielded against, though that's mostly because Russia doesn't actually have a hypersonic missile. Iran, fortunately, doesn't have hypersonics–where did you get the idea they do?

Decoys are an issue. Two radar systems not really an issue.

> patriot is <5-10% effective in footage review from early Iran conflict before they started using hypersonic multiple vehicle missiles

Patriot has been about 33% effective. Becasue we fire 3 missiles at each target as standard course. Which means close to 100% intercept rate when targeted. "When targeted" may contain some bullshit, but it's a hell of a better bet than anything Postol is peddling without ample fact checking. (His record has been spotty for a while, particularly when it comes to OSINT.)

Put it another way: Iran has hit...tens of meaningful targets? In America and Israel? Do you think their missiles are just that terrible that they fire hundreds to thousands and a vanishing percentage go where they're meant to? (I'm ignoring that many of the high-value hits were with drones. Not missiles.)
