America favors bombing countries in order to achieve military objectives, for a lot of reasons, of which foremost amongst them is that such bombing risks few American lives at the expense of the designated enemy. Americans are the kings at using drones in which no American life will be sacrificed if such a drone is shot down, compromised, or to suffer failure; so too, countries without an effective defensive air force are virtually incapable of taking down our aircraft, for their anti-aircraft armory seldom is able to touch our aircraft which effectively rules the sky. In fact, the only time that those conducting such bombing are in any real danger is when bombers are called into emergency action in which they are needed to dislodge an enemy from their positions, so as to free up or aid our soldiers in their conduct of ground missions, or as in the aid of the successful retreat or evacuation from American positions which cannot be successfully maintained.
It is important to recognize that each American bombing mission is approved with corresponding objectives and goals by the respective commanding officer before such a mission is commenced. This means that what particular air bombers are or aren't going to be used, or whether drones are preferred, what type of bombs, the target for those bombs, and the overarching goal of such bombing has been confirmed before such a sortie is sent out for its given target. This means that the bombing mission is known before commencement, though, there are contingencies made in order to deal with foul weather, or unanticipated anti-aircraft activity or enemy aircraft, that could indeed change the direction of a given mission, but none of the air missions are random in the sense that drones and bombing is done indiscriminately and without a particular object and target in mind, whether that be primary, secondary, or tertiary.
All of the foregoing would indicate that in order to know whether such bombing is successful or not, that those that order such bombing must know whether such targets have been successfully engaged, and how successful or not those missions have been. Additionally, it is of vital importance, that such bombing does not violate the governing laws of war, which specifically forbids "… the deliberate or indiscriminate attack of civilians and civilian objects," of which, it should be the objective of any country that is dropping bombs upon another, to do so in a manner that such bombing is actually necessary in the first place, while also taking into account that civilian casualties and the destruction of civilian infrastructure must be minimized.
This signifies that when one country bombs another country, that each bombing sortie must be evaluated as comprehensively as possible, with independent oversight, so as to ascertain who and what has been killed, injured, and damaged by such bombing raids, so that, taking this documented information into account, a wholly complete picture of what has really occurred will be evaluated by independent sources, in which not only will such information, provide invaluable feedback for the countries doing such bombing so that they can learn from such, but that, If necessary, sanctions and war crime charges can be actuated, for egregious offenses against humanity.
Those that drop bombs on other countries, have a responsibility for their actions, in which, if their purported goal was to specifically attack the enemy and the enemy's infrastructure, than they should not only welcome but actually desire real feedback as to the actual damages so done, in order to learn from and to amend their procedures going forward, which is, at a minimum, the responsibility and the duty that they owe their fellow man.
