Why do we go to war with countries who may be developing Nukes, or may have WMD's, but, as it turn out do not, when there are terrorist harboring countries with nukes who are allies of the US and who do not get attacked?
For example: Pakistan-was the worlds largest anti-US terrorist harboring country prior to 911 and possibly still are, if Saudi Arabia isnt.
Or: North Korea, who has in the past declared at least 1 nuke, possibly as many as 4 and have threatened to use them if we dont knuckle under to their wishes, which is esentially blackmail?
And if these countries, Iran and N korea, are on the list for possible US attack, wouldnt it be wise for them to develope the Nukes for sel;f defense? What kind of fool arse country would try to defeat the US in a conventional, dont break the rules, war?
