[quote]we have the power to end humanity.[/quote] It's pretty impressive how far we've come this past century. I doubt that the US and Russia, were war to be declared, would launch all of their nukes in all directions. It would be done in the form of precise, coordinated strikes. Even in the event of nuclear war, most countries would likely emerge intact. Although, radiation and nuclear winter resulting from the destruction of population centres would affect the surviving nations for a very long time.
