Fun fact: Drones can be disabled by blinding them with excess visual or IR noise, jamming their control signals, or applying a fast-moving chunk of metal of appropriate size.
Further, drones are still limited to mostly open spaces. You can't clear a room with a quadcopter (yet), and a Predator missile strike is just as likely to kill loyal citizens as it is to kill the target.
Tanks are easily outmaneuvered by humans on foot. Planes cannot take a building and leave it intact. Drones have electronic weaknesses in addition to the usual flaws. And nukes are practically a joke--the fallout, physical and political, would ruin any nation.
TL;DR: Drones make terrible soldiers. Why do you think ISIS is still live and kicking?
But a stupid tactic is one that may result in defeat.
Sun Tzu's slightly-less-famous quote--"If fighting is sure to result in victory, then you must fight"--has two meanings, like a lot of Asian philosophy does. The obvious part is, as the saying goes, sieze the day. The less obvious part is that you should only sieze the day if you know you can hang onto it.
In the case of nukes, only a damn fool would nuke his own food supply or factories, or perhaps a spiteful loser.
That is just the reason, many countries and many people of a specific fraction already arm themselves against revolutions.
What fantastic innovations are robots and drones!
