Here's some post by a dude who claims he has quotes. Unsourced.
The Pentagon adopted the two-war requirement after the Gulf War. It was designed in part to discourage a potential aggressor, such as North Korea, from making trouble for U.S. forces in the region when this country is caught up in a major war elsewhere, such as the Middle East.
Indeed, some speculate that China may try to invade Taiwan if the US is busy in Iraq. Similarly, some published reports have supported fears that Ariel Sharon might spend the last days of his administration pushing Palestinians out of the Territories while the US messes around in Iraq; at least one report claims he would order such an action the day a large-scale invasion takes place. Chances are, we could name a few other countries that might try to use the "preemptive defense" doctrine that Bush has been trying to use on Iraq for months now.
On another note...
"Iraq is a part of the war on terrorism," Rice said
Separately, homeland security adviser Tom Ridge contended: "Clearly the president and everyone is confident that we can deal with the terrorist threat and, if we have to, deal with Iraq as well."
So... ummmm... is Iraq part of the terrorist threat, or a separate issue? Depends who you ask on what day, it seems.
Meanwhile, everyone continues to make decisions for Iraqis and Kurds, while not asking what they'd like to see in a post-Saddam Iraq.
