I do actually sorta see Hegseths point here. If the President ordered it, and he was just carrying out the orders. Either A) it was lawful, or B) it was the President breaking the law. I certainly don't think "I was just following orders!" is a valid defense, but if Hegseth is impeached, then Trump is de facto, also guilty, and should be the one ultimately to blame, as are all officers in the chain of command. CENTCOM on down to pilots (I don't think we should be prosecuting anyone under the rank of Major though).
