There will be a hot war before that happens.
If that is what they really want, they had best be careful what they wish for.
No, there won't. Stop blowing hot air. I've heard the same nonsense for years now from conservative. "If you cross this line, there will be war." to "Ok, you've crossed that line, but if you cross THIS line, there there will really be war" to "Now you've gone and done it. Cross THIS line and I guarantee there will be war" to the present.
Civil war should have happened in Obama's first term, if not sooner. The US is hosed.
