Combine the decreasing specific impulse of airbreathing propulsion systems and the low lift-to-drag ratio at high Mach numbers, and it becomes difficult to sustain fast flight:

Missing on the chart is subsonic turbofans with 6000-10,000s Isp!

Todays video is about Scramjets, explaining why regular turbojets and ramjets can't operated at hypersonic speeds and how Scramjets solve these problems, enabling airbreathing jets like NASA's X-43A that operated at Mach 9.6!

Hydrogen is shot by a NERVA-derived reactor into a ramjet-like duct, heating the air and then adding more energy via combustion. The engine achieves 800 to 6000s Isp at Mach 0-25, for a mission average of 1277s.

-Drag in air rises faster than oxygen supply
-Oxygen/Drag ratio doesn't change with altitude
-Intake area to vehicle cross-section area ratio fixes a max speed of ~Mach 6
These limitations define what's possible with airbreathing ascent to orbit:

The things on the front are not really wings. They're basically aerodynamic shrouds for the airbreathing engines used to fly back to the launch site

Confusingly, the MHD ducts are used to extract power from shock-ionized hypersonic airflow to start up the fusion reaction.

even with🌐 shortcutJASSM and other cruise missiles just as manned airbreathing airplanes need altitude to reach advised range and Ukraine has lost fighter jet at 200km engagement range to Axehead missiles. If more Felons are operational soon EU is in trouble in air domain without US support.

You're essentially saying "why don't we used staged space rockets to fly from UK to Florida?" and my answer is "airbreathing jet is much smaller"
Not quite as fast, but much smaller and lighter given half of what it needs to work is in the air.

I dont think Israel worries much about airbreathing threats, especially not the cheap fixed wing drones. They can outproduce Iran in terms of kinetic defenses there. The interceptors for ballistic missile defence are a somewhat different story.
