Do you have access to a computer and basic Google skills?
As for preciseness, the newer ballistics have precision of over 90% (thanks, US designed chips). Older ones probably 75%. Their biggest weakness is access to chips.
And the imprecise hits are coming from the Tochka-Us, an old system that mostly the Ukrainians are fielding - but maybe pro-Russian Ukrainian separatists forces some, too.

Ok, so they are bombing civilians on purpose, is that what you say?
It is no secret that much of the good Soviet tech was produced in Ukraine, both tanks and missiles, and without maintenance they won't be as precise as they were supposed to be. And for some reason Ukrainians hasn't wanted to do maintenance on Russians tech the last few years.
That said we've also seen plenty enough evidence that Russians shoot civilians on purpose.
Thus far, Russian stuff that actually works is the one from USSR times.
Are you really sure that the Russian cleptocracy that sends sappers to the front line with wooden bricks wrapped up as TNT (yep) and styrofoam wrapped up as dry rations for "liberated" civilians are somehow capable of maintaining a fleet of strategic missiles at 1/100 of the budget that US spends to maintain theirs?
I'm not.
But I am afraid that if we give them 5 years they will manage to get something working.
And that scares me more than the thought of angering Putin right now.
Luckily I don't have to make this decisions, we have people in Nato who knows extremely much more than me. If they tell me to show up I do.
