I think you are overestimating the precision of unguided rockets. Lets eyeball this:
Lets assume the rocket flies ten kilometers, which is on the short end of things. As it is subsonic, it at best could reach a speed of 300m/s (hypersonic is above 343 m/s). Since we are looking at an arc for the shape, lets assume a launch angle of 30°, making it a fairly flat arc. So the speed in ground direction then only is 86% which is cos 30° or in total 260m/s. So that rocket has to fly at least 38 seconds.
Taking just a sideways wind, assuming a gentle breeze on the beaufort scale, at about 4.5 m/s, that would result in a deviation of 171m over the 38 seconds. But now you get wind from the back or the front, which gives the rocket upwards or downwards drift. Or the wind isn’t perfectly sideways, so it actually changes the direction the propulsion is pushing too. Over such a range you also get changing wind speeds and directions…
You face the same thing with artillery. Which is why it is usually used in batteries and to cover an area, rather than hit a specific target. Although Artillery is easier in the sense, that the propulsion happens right in the beginning and is aimed correctly.
If we are talking guided missiles, it is a very different story, although i would be suprised if Hezbollah had access to GPS guiding or similiar high precision tools.
If you think your dad was sent to fight against the Nazis for ideological opposition, i have bad news for you. Maybe he personally fought out of that motivation, but must countries at the time were either fascist themselves or on the edge to fascism.
If you look at the US there was the ongoing genocide against native Americans, the racial segregation, eugenics, despicable human experimentation carried out on minorities, concentration camps for Japanese during WW2… Even the pledge to the flag in the schools was something Hitler admired and copied. Until the German Nazis became unpopular in the US the pledge to the flag with done with the “Bellamy Salute” that is the same as the Nazi salute. https://en.wikipedia.org/wiki/Bellamy_salute

The truth is, they never left.
What is different though is that after WW2 it was understood which social problems, in particular fucking over the lower and middle class, create the breeding ground for fascism to be successful. Since the 1980s with Thatcher and Reagan and then the neoliberal wave over Europe, we had 40 years of deliberately empowering fascism. Now they reap what they sew.
