Really? You think that is a no?The existence of a terrorist organization that hates America does not automatically make that organization a threat to national security.Yes, it is. The fact that is not crystal clear makes no sense whatsoever. They are a terrorist organization and they hate America. There really is no way around that. Would they attack us - that is a resounding yes. There certainly is a debate to be had as to the best way to deal with that threat and/or what military actions will help or exacerbate the problem but there is no question that they do pose a threat.Is ISIS a serious threat to U.S. national security? Honest question. Is there any serious threat that ISIS will come blow up the U.S.? I really don't think so. They don't have that capability. Furthermore, the regional powers are against ISIS, and would likely take care of the problem without U.S. interference.
The U.S. has historically made things worse when interfering like this.
You are asking the wrong question. The question is not would they attack us, it is can they attack us. Do they have the capabilities? Is there a reasonable chance that this will happen? The answer to that is a resounding no.
The fact that nearly every country in the region is against them - countries with military capabilities of taking them out without U.S. help, by the way - makes the threat even less serious. Is Isis a horrible group? Yes. But a horrible group does not a national security threat make.
You are sorely mistaken about what a modern day 'attack' is then. It is no longer about missiles and ground forces. Its about men with briefcases.
Or did you miss the fact that the last attack was accomplished with box cutters?
