There are a lot of 'threats' in the world...almost all of them worse than Iraq. Iraq was first because it was convenient, and we 'knew' we could win because they were weak from years of sanctions. Imagine if we'd actually gone to 'war' with a country that had some real strength. It's pretty much an unethical war...and Ws arguing the ethics of stem cell research in the debate. We can kill 18 year old soldiers for no good reason, but we can't use frozen embryos that will be destroyed or kept frozen for the BEST of reasons?
