Rubio Doesn't Understand ...

 ... that quantity, while very important, means very little when you deal with generational quality gap. 

The 12-day "war", in reality beating the crap out of Israel, demonstrated a manifest ineffectiveness of US air defense/anti-missile systems. No matter the spin, the WSJ may declare whatever it wants: 

Before Any Strike on Iran, U.S. Needs to Bolster Air Defenses in Mideast. The Pentagon is taking steps to better protect Israel, Arab allies and American forces if Iran retaliates. 

But the capability gap is not a figment of imagination of Andrei Martyanov, of which I wrote for more than a decade, it is one of those "Capability Surprises" about which I also wrote (I called it a Revelation Mode) and made a video about this document.

And then there is risk avoidance and after that--risk aversion. The foundation of the US perceived global power--the US Navy's Carrier Battle Groups lost physics and mathematics contest to anyone who understands Missile Combat, Salvo Model and has technological wherewithal to produce and field even a previous generation of weapons, which make CBGs fat prestigious targets. Iran has such capability and whatever else was provided to her by Russians and Chinese. Now we wait and see. I speak about it and more in my latest video which should be up shortly.
