No, the US is likely to be the other side of whatever the next major conflict is. If it's a major conflict it will likely end in nuclear war, even if it doesn't start that way. The US is the last place you want to be. Australia, New Zealand, or South America would be much safer, and the climate still amenable to growing food during the nuclear winter. In Australia and New Zealand the land area to population is also very high, which helps in a famine situation.

I like to think (hope? Dream?) That there won't be any more major conflicts now that we have nuclear weapons. But betting against the stupidity of politicians seems like a risky proposition.
