The answer is simple - we hit their nuclear bum storage facility. And they have a meltdown situation at hands- much smaller probably than chernobyl, but still a meltdown.hence they ordered boron from Egypt, which they got in a egypt military cargo plane.
I am not duffer, i am MSc guy in math- i can put 2+2 together and if input is solid,output too is, in my mind- if you have 'strikes' on a nuclear weapons facility and then you order boron, it means ur uranium or plutonium is on fire and melting down. What scale, how much - that obviously i dont know or cant tell.
But just to give you an eg, chernobyl needed about 5000 tonnes of boron dropped on its ass to stop being reactive ( it is still minorly reactive, coz u cant really ever kill a nuclear fission reaction, you can just blanket it in neutron asorber-which is boron- and let boron keep eating its neutrons, so reactivity dies/drops and its just faint glowy stuff to put it in idot terms).
A military cargo plane can probably hold 100-150 tonnes of boron. So scale can be inferred from this, but not confirmed for sure but the arrival of boron can be confirmed for sure,because you only ever need it when there is a meltdown.
If your uranium facility's uranium storage tank is broken and uranium ore or uranium fuel is exposed or leaking out, you want lead.Lead is what absorbes the radiation from uranium that affects us - alpha,beta and gamma radiation.Thats why you have lead sheilding in CT scan rooms, not boron. You want boron when you have an out of control reaction getting hotter and hotter and catching on fire and making a 1500C fire like chernobyl turned into- which you can do to a nuclear bomb by blowing up another bomb over it ( i already explained why you cannot set it off in a nuclear reaction a few pages before, go check if you have questions). A meltdown of ANY scale is a big deal. period. Even if its a kilo of uranium on meltdown, its STILL a big deal and will make any engineer shit his pants on how to solve this, fyi. coz solution is possible, but not easy.
So Amreekaa went 'WAAAAAAAAAAAAAAAA stop now !! N word is invoked, we are sending plane from US energy comission that detects radiation leaks to fly arond and see, if you drop bum on amreeki guy, there will be hell to pay'.
And since we are not duffers like Saddam Hussein to go 'FAAK U AMREEKA ! HAIWAN ! SHARMOUTA ! COME I WILL DROP BUM ON U TOO IF YOU MESS WITH OUR KUWAIT..ERR PAKISTAN', we acted reasonably and said 'ok. ceasefire. go check it out'.
Thats what is happening.
