I am not. When you are flying to do drone attack, you still have to defend yourself against enemy aircraft and anti-aircraft units like AA, and this means you are doing both attack (destroying your target) and defending your mission and your aircraft from getting shot. I am not familiar with how air battle works, but my understanding is, there are fighter jets to protect bombers and drones. But still, you need to kind of defend yourself. Bombers have machine guns equipped for example so bomber can still defend itself.

There really hasn't been a situation like that since the Korean War. Modern warfare relies heavily on radar and ballistic missiles. Fighter jets usually operate far ahead of any ground forces or bombers eliminating threats before they even pose a risk.

Drones are quickly replacing aircraft like the A-10 because the primary threat to these aircraft comes from ground fire, drones however operate out of visual range.
