What, exactly, makes you think we ignored the problem, other than you believing so?But we simply ignored them while they continued on the road to get nukes
First off, I remember quite a bit of negotiation and posturing in the news in the past year and a half.
Secondly, even if there hadn't been anything in the news, what makes you so sure nothing was going on. Are you consulted in all matters of foreign policy? If you are, then why didn't you tell us we were in talks with Libya? That would have been interesting to talk about.
