Attack on Iraq would be a dangerous precedent. Any nation, which feels threatended by another can be attacked then in such a manner. China can then attack Taiwan without repercussions, India pakistan, Israel any Arabic nation they feel like, Russia some neighbours they have problems with.
It would initiate a ew era of might makes right.
Saddam Hussein has surely not a pretty character. But the reasons for an attack aren´t really consistent. So what if he builds mass killing weapons. Any chemistry student in the USA can synthetizse poisons to wipe out lots of people once they make it into drinking water.
The so called war on terrorism is a huge hoax. There are still Christian terrorists in the USA, which aren´t bothered at all. Christian terrorists all over South America and Europe aren´t bothered by the USA at all. This so called war for terrorism is just a silly excuse to push through police state laws and do anything to keep to the own interests.
There is nothing wrong for a nation to look after its own interests. But using military force to defend only its own interests with not even rudementary backing from its own allies, that draws a line, no one should cross. When USA is doing that, what hinders China, Japan, Russia, India do the same? Where will it end?
