How would they throw it at us? Like, logistically I don't see how it is possible.
There was a speaker on TED.com talking about how the US military can defeat any nation in the world. He went into detail about how much money, carriers, ships, missiles,,,, everything the US has. We can overthrow just about any nation in the world in a matter of days.
The speaker also said this is not a good thing.
The opinion was that if a nation knows it can not defeat the US in conventional warfare, that nation might resort to striking the US with a nuclear weapon.
If a dictator knows he is going to be overthrown, what does he have to lose by nuking LA, Houston, New york, Washington DC,,,?
So what if the nation is defeated a few weeks later. So what if we resort to nuclear weapons in response. With the way our cities are designed, we would be the loser in the long run.
We can not displace LA, Houston, New york, Dallas,,, size populations. Nor can we afford to rebuild entire cities. How many years has it taken to rebuild the twin towers? How are we supposed to rebuild entire cities?
