1. Countries who start wars rarely do so from a position of weakness, and rarely have more will to fight than whomever they are invading.

2. Drones are more effective in an asymmetric fight. The stronger , more developed side gets hit harder. Which is why Russia and the US is having such a bad time with them. They are both starting shit with countries that have far less to lose, and have far more resolve to fight.

So yes, it is in fact a pretty easy answer.
