I couldn't find any explicit call for the use of nuclear weapons but I found the following he wrote on the War On Terror in 2002 [1]:
> If the war on terror is to be won swiftly, Mr. Bush must not lose sight of the war's twin imperatives: a decisive counterattack and a total unwillingness to appease our enemies.
> Baghdad remains the next stop but not the last. We must also have plans for Tehran and Damascus, not to mention Riyadh. The tactics will vary, but the goal -- total defeat of terrorism -- is clear. Once American ground troops are in Iraq, the message must go out to all terrorist sponsors that this game is up.
> Those who instigated the current war must remember that Coventry and Pearl Harbor backfired on Dresden and Hiroshima. There will be no peace in Gaza, no freedom from fear in Jerusalem, until we have prosecuted the war on terror in Baghdad, Tehran, Damascus and elsewhere. U.S. leadership saved Europe from fascism and communism. It is again the last hope.
With a funny quote:
> In another striking resemblance to World War II, Russia could once again be America's valuable ally. Despite Vladimir Putin's record in Chechnya and on human rights, he is way ahead of "Uncle Joe" -- the hero of the Western liberal press from 1941-45.
