But a stupid tactic is one that may result in defeat.<p>Sun Tzu&#x27;s slightly-less-famous quote--&quot;If fighting is sure to result in victory, then you must fight&quot;--has two meanings, like a lot of Asian philosophy does. The obvious part is, as the saying goes, sieze the day. The less obvious part is that you should only sieze the day if you know you can hang onto it.<p>In the case of nukes, only a damn fool would nuke his own food supply or factories, or perhaps a spiteful loser.
