Like how Bush failed to stop the terrorist attack on 9/11, or Roosevelt failed to prevent the attack on Pearl Harbor. That's the thing with covert attacks, their pretty difficult to stop. But much like Trump you seem to be full of hot air and not much else (see. Intelligence). And like Trump you seem to be more interested in placing blame than looking for resolutions. Look at it this way though bud, Putin won't have to be covert for the next four years because he can just tell Trump what he wants and he'll probably get it. All covered in gold no doubt.
