How did both president nixon and president carter influence foreign relationships

Well think about it ...

President Carter once said ... "For too many years, we've been willing to adopt the flawed and erroneous principles and tactics of our adversaries, sometimes abandoning our own values for theirs. We've fought fire with fire, never thinking that fire is sometimes best quenched with water. This approach failed, with Vietnam the best example of its intellectual and moral poverty. But through failure we have now found our way back to our own principles and values, and we have regained our lost confidence."

He refused to continue the past practice of overlooking the human rights abuses of our own allies.
