There's some good information there. I found this item particularly interesting:

Despite this early show of solidarity, NATO would face a crisis little more than a year later, when on 10 February 2003, France and Belgium vetoed the procedure of silent approval concerning the timing of protective measures for Turkey in case of a possible war with Iraq. Germany did not use its right to break the procedure but said it supported the veto.

I remember when this happened. It was quite a bizarre position for these member nations to find themselves in.
