How can I turn an if-else statement with a nested if statement into one ternary statement?

This is the code that I currently have:

        if (isStandard(statement)) {
            if (isPerfect(statement)) {
                alert("This is a perfect palindrome.");
            } else {
                alert("This is a standard palindrome.");
            }
        } else {
            alert("The statement is not a palindrome.");
        }

I want to be able to turn this into a single ternary statement, where the strings inside the alert() will be the value returned. I am aware of how to do this for if-elseif-else statements, but not for nested ifs.
