No it doesn't, because L2 is behind the moon and L1 is in front. Now,
launching towards L2 with a higher velocity might let the rock loop around
back towards Earth, but there's no guarantee that it would actually hit
the planet. There probably are trajectories that would work, but you'd
have to be quite precise and your accuracy would be poor.

I'm not sure what the value would be. Once you reach L1 you're basically
at the Earth or moon, so I'm not sure that there's any benefit of having a
station there at all. The only thing I could think of would be refuelling
prior to lunar landing, but your station-keeping requirements at L1 would
probably be so large that it would cost you far more than loading up with
enough fuel prior to launch.

Then you'd probably be taken to court immediately for reckless
endangerment. Anything stationary at L1 which loses station-keeping
control will probably drop onto either then Earth or Moon. No-one will be
happy about you putting a station in such a "fail-extremely-dangerous"
location.
Perhaps you could do this if you had a legitimate reason to use it to
export materials to Earth, but that seems unlikely and I'm still not sure
that people would be very happy about you doing so.

Well, that depends... the main disadvantage would be that I'd probably need
a rocket to turn the warhead around and fire it into the lunar surface.
Bad, but not insurmountable. I'm not sure whether there is a direct
trajectory from the Earth to the far side (I suspect there isn't), but if
I'm going to have to use a rocket anyway I'd probably want to choose a
course which leaves me travelling slowly a long way above the moon and
come in from that side. Slower, yes, but I would have thought that that
would take me further from the surface and make it harder to detect.
Note that we've already demonstrated that you can't realistically attack
the Earth with a mass-driver unless you have a massive energy-production
facility, which is why you went over to near-earth asteroids instead.

Really? If the lunies come out on TV ranting about attacking Earth if they
try to stop their independence then the population will sit back and
applaud? I suspect that the closest historical event would be the Cuban
missile crisis, and although the US didn't attack Cuba they probably would
have done if the Soviets didn't give in.
Note that you've already said that if the US launched its space fleet to
the moon as a blockade you'd shoot them down, so that I'd have to launch
an attack directly from Earth. If you won't do so, then my fleet will be
orbiting a couple of hundred km up and just itching to blow you up.
Noone's going to complain about me enforcing UN-imposed sanctions against
dangerous revolutionaries like yourselves, and if you attack we'll be
forced to retaliate in self-defence.

ROTFL... have you ever investigated the history of groups who claim their
"recognised right of self determination"? History is full of fanatics who
think that all they have to do is go to the UN requesting independence and
they'll fall over themselves to give it to them. I mean many countries
still haven't even accepted Taiwan as a sovereign state!!!!!

Again, is this a penal colony or a corporate colony? If it's a penal colony
then the government already have the launch vehicles to ship a million people
to the moon, and a warhead is no big deal. If not, then they'll have bought
them from corporations.

Aha... so you have a monopoly on the technology, no competitors and refuse
to sell it to anyone else? I might just as well claim that the USAF will
lift off to bomb you from their captured alien saucers; it would be just
as realistic.

Even when you're threatening to drop rocks on Earth cities? How many
casualties are people really willing to accept in order to not use nukes?

And people on Luna won't have relatives on Earth? So the lunies will be
happy to destroy the Earth's cities where their relatives live, but the
Earthers won't be willing to do the same?

Sorry, you went from talking about 'cost' in terms of people killed to
cost in monetary terms. I was still talking about the former.
But people pay taxes to the government to protect them from lunies
dropping rocks on their heads at thousands of meters per second. How many
people really care if a cruise missile crashes as compared to a soldier
being shot? Which costs more? People care much more about the lives of
their soldiers than the cost of weapons.

Does the word "projection" mean anything to you? I want to see if there's
a realistic scenario for a war between Earth and Moon. Yours seems to rely
on a) having a million people on the moon and b) the Earth governments having
essentially no prescence in space at all. This is incredibly unrealistic
*unless* there had been a general and dramatic reduction in the power of
Earth governments. I certainly hope that happens, but don't see it in the
next couple of decades. That would also seem to eliminate the neccessity.
