Asteroid impacts are so destructive because they are moving at very high speeds relative to the earth, often more than 20 km/s. If you just lifted some big rock up and let it fall down again it wouldn't be going anywhere near as fast, sure it would probably fuck up whatever it landed on but the energy required to do it would be a waste of time.

Not directly.
Firing something into space and letting it fall back is just (partially) converting the energy in the fuel into the kinetic energy of the rocket and then back into heat when it hits.
Might as well just explode the fuel at ground level.
Your scheme doesn't created any energy.

On the other hand, you must be aware of plans to deflect an asteroid away from Earth if it was on an impact trajectory. Works in reverse too. Move an asteroid which was scheduled to barely miss us so that it hits.
The energy is already in the asteroid. We're just making a minor adjustment.

Guided Tungsten Rods seem to do pretty good

Right. "Dropped" from the Moon.
Fool.

>>9685522
No, not by launching but from redirecting asteroids from around the orbit into earth's atmosphere.
The americunts already have got this shit, look it up on the (dark)net.
Even more, once the freemasons will be angry, they will bomb the shit out of africa and other shitholes of the world, especially the mideast, but this after jews will be long gone from that place. Since n group of freemasons are friends with the heebs.

So do a gravity-whip around something else before it heads back,

This is a good opening for a yo mama joke.

That doesn't really address whether it would be possible. Yes, it would be grossly inefficient and you could use the fuel to make more destruction in better ways. But you put emough mass up and get it moving, it fo=does what mass moving at that velocity does when it hits Earth, however it got there.

To do what OP wants, you either need to get a small (comparably) mass moving Really Fucking Fast (tm) or a Big Fucking Huge Ass Mass, in which case it can come in (comparitively) slower.

In either case, looks like you'll need multiple launches and, as you point out, stupidly inefficient use of your world-destroying budget.
But given the decision to destroy the planet the long dumb stupid expensive way, it could be done.

Ya just slingshot the rock around the sun.

Came here to post something like this. If you could sling shot it around the moon it might be able to do some damage. Not in physics though so I could be dead wrong, maybe a larger object is needed.
