If Obama had held a rally where he said, "Yeah, North Korea may hit back at us, but it'll be worth it... Let 'em take out Corpus Christi, let'em take out Oklahoma City, it's a small price to pay," there would have been riots in the streets and an impeachment vote shortly thereafter, with several Democrats joining the republicans.
That's the difference between them. The conservatives are ready to riot at any moment and delight in the use of force; Democratic leaders are timid debate club nerds.
