Lame attempts at propulsion. Go to Mars? Will it take 1000 years?

I don't think that there is much of a threat from Yosemite... but Yellowstone is another matter...

Humans have needed to live somewhere else than on Earth since around 1948.

Be that as it may, humanity is not going to colonize Mars. But if the
1% want to try it on their own nickel, I'm all for it. No rescues, no
resupplies on the public nickel.

So while it may take a while, a nuclear stalemate favors the bad guys. For
freedom to really survive, we need to get far out of the reach of the ICBMs
of despotic regimes.

It's not much of a technological leap from ICBMs to InterPlanetary
Ballistic Missiles. Then what?

So it might seem. After all, an ICBM is a rocket, and what do people go to Mars
in? Rockets!

But it's not as simple as that.

An IPBM that takes two years to get to its target... can be evaded and
countered and so on. Making IPBMs as deadly to Martian colonists as ICBMs are
to people on Earth *is* a technological leap.

While that was clearly a slip, of course there's a threat from Yosemite... but, fortunately, we have Bugs Bunny to defend us against it!

No. As of today, Yosemite is passé. Apple released OS 10.11 "El
Capitan" and all is well.

True - it would be more efficient for an attacker to go to Mars,
present to be peaceful, and then launch an ICBM from Mars.

The major security hazard is to bring people to Mars, because it's
people who make war.

Hitler's army invaded Poland. The UK declared war on Germany. Who started the War?
