Less than a third of the world’s surface is dry land—the Pacific Ocean alone is larger than all the continents combined. So the chances of an asteroid hitting land would be about 11%...and less than 10% of the land area of the earth is the US. So there is very little chance that an asteroid which hit the earth would hit the US. It might actually hit some place that we would prefer to have demolished.
30% of the Earth’s surface is land, so that’s the chance of a land impact.
An impact on the sea of an object that size wouldn’t be a picnic, and could have a lengthy negative influence on the survival of our civilization.
There isn’t any particular apparent preference for impacts on or near the Equator rather than the polar areas.
We have a large moon by Solar System standards, so there’s also a slightly reduced cnance of any surface impact on Earth, as the Moon would screen out some of the random arrivals.
