Wrong, laser guided bombs are old tech, since the later Vietnam War days. If they did have bunker busters, then India must have done something wrong with them because they ordered more bunker busters then. Helicopters and fighters can do everything the drone can, BUT if you have any understand of basic weapons systems, then you know drones can stay aloft longer, and there is no fatigue when the drone pilot can be replace by another.
Copying for previous comment:
The same bombs that UAVs can carry, fighters and helicopters can carry. In fact, because of the limited capacity of modern UAVs, fighters and helis can carry far more, making them far more deadly.
Funnily enough, laser guided bombs are what most UAVs carry, including the TB2. In fact, the US Predator/Reaper drone carry the hellfire laser guided bombs. The various Chinese CH-X drones carry the Blue arrow laser guided bombs, and the TB2 carry Turkish Roketsan designed laser guided bombs. So, even if we were to say that India didn't use BBs, and instead used laser guided bombs, my point would be even stronger.
Now, drones can stay aloft longer, yes, but in practical terms we aren't seeing UAVs actually staying in the air for more than 5ish hours, which is around a similar time frame that most modern fighters can and DO regularly.
This idea that drones are inherently superior to fighters is flawed. There is a reason that despite having a lot of drones, the US still relies heavily on air strikes from fighter.
Drones also can be lost easily, due to their slower nature. In other words, a prepared enemy is more likely to shoot down a drone than a super sonic fighter jet.
