Piper,
I did a Google search for: (on the search line as below)
will north Korea attack America
There are many more than I can 'see' today, and at the bottom of the page there is a line with subjects to click on, choose Groups and the 2nd message is a link to an old article about Iran training Terrorists.
A site that will cause you to think, is:
Jewish Task Force

Looks like good current news on the war here:
Federation of American Scientists

Or there is a clinton era secret report, "Emerging Missile Threats to North America During the Next 15 Years" Nov. 95
