how can you say "the people" like that. First of all, realize that a war would affect all the people in the country, regardless of whether or not they support the Saudi royalty and/or terrorist. Next, realize that Saudi Arabia is a monarchy, so you have no way of knowing how many people support the government, because they have no way of showing their lack of support. And finally, realize that Saudi Arabia is a country of 25 miliion people, and if you believe that a majority actively support terrorists, you need to sit down and consider your views on the rest of the world.
oh and, after you have realized all that, it might also be helpful to realize that by any meaninful standard, Bush and Co are terrorists, if not the far more severe agressors, so any country that feels like invading the US (say, Nicargua, Iraq, Lebanon and so forth) would be justified in doing so, especially given that evidently, so many people support Bush (or Kerry, who also voted for the war). Its not wise to chastise others for supporting terrorism when you don't have the moral high ground.
