By Yemen do you mean southern province of Saudi Arabia >

And another $4.3B in 2024, and another $4.3B in 2025, and so on.
Certain parts of the worlds have become too destructed to ever be repaired. Yemen is one of those parts. >

How much was made by the USA and the west from selling weapons to Saudi Arabia to bomb Yemen? Probably much more than $4.3B. 
You see, that's the value of war. Even if the west pays all $4.3B it was still profit.
Edit: I didn't say only the west is doing wrong. I just asked about the war industry. >

Maybe focus on Saudi Arabia and Iran for this shit show......
They are the biggest contributors for their dictator proxy warring.
