Would the FAE (Fuel Air Explosion) be so powerful as nuclear weapons?

Would the FAE (Fuel Air Explosion) be so powerful as nuclear weapons?

1) The energy sources of nuclear weapons are different than conventional weapons, and that makes a comparison of them difficult.

The nuclear weapons are acting a little bit different way than thermobaric explosives. The thing, what makes them hard to compare is that nuclear weapon would get its power from the fission or fusion of the nucleus of atoms, and that weapon is sending the electromagnetic, electron- and ion radiation to the target. The beta-radiation is fast electrons, which are impacting the target, and release their energy to it. That causes that the target is heating to extremely high temperatures. 

The beta-radiation would be fast electrons, and alpha radiation would be the helium ion, but also gamma-ray bursts would cause the horrible situation in the target area because it can destroy the DNA inside the human body. When those things hit structures, that thing would be heathen, and that causes the effect, where the vehicles are melted, and even the short term radiation would transfer high energy levels to the target. 

And if the target is made by metal, that means that more energy would transfer to that than the target would be some less thin material. In the metal, those particles would transfer very much energy to the object, and that causes the extreme heat to that target. 

2) The electron and ion radiation along with high-energy radiation would make nuclear weapons superior to conventional weapons.

And the small-size nuclear weapon, like 0,5 kiloton neutron warhead can cause much more damages than the thermobaric explosion. The thing that is boosting the effect of a nuclear weapon in the nucleus radiation like fast neutrons, what can kill people even the structures seems not damaged. The electromagnetic radiation would destroy electric equipment, and that means that nuclear weapons have more abilities to make damages than FAE. 

The temperature inside the fireball of nuclear weapons is millions or even billions of degrees of celsius. And even smallest size nuclear weapons would form the fireball, what temperature is tens of thousands of degrees of celsius. The full damages, what nuclear weapon causes are depending on the time, what the fireball stands in form. The effect of a nuclear weapon is that the steel and rock around it are starting to vaporize. And the nuclear material, what is used in bombs is really expensive and dangerous. 

3) Pressure wall travels away from the explosives with the speed, what the explosive burns. 

The thing that makes the blast effect of a nuclear weapon is the expanding gas as well with a thermobaric explosion, but the nukes would send the pressure wall far higher speed than FAE, and that thing is called the shockwave. The speed of firefront in explosive determines the blast effect and the speed of the escaping gas. And in a nuclear explosion, the speed of fire is very high, because the nuclear reaction is causing the sound, what is called the shock wave. Also, the rising fireball causes the effect that air is starting to pull in the fireball, which increases the damages. 

The FAE bomb is made for simulations of nuclear detonations. They are really powerful, and the destruction radius between those bombs is sharp, but that weapon doesn't have the electromagnetic radiation for boosting its power. So that's why the nuclear explosions cannot compare with the conventional explosions. The fireballs of nukes are hotter, and the other effects make those things more deadly than any conventional weapon can be.
