The US can stop ISIS. The US does not want to, because we&#x27;d rather not kill a ton of people. If the desire were there (and I surely hope it never is) then killing them all and everyone nearby would take care of it.<p>Thankfully, an unwillingness to do what it takes to eliminate this threat is not a big problem, because it&#x27;s not a big threat. The deaths in Paris were sad, but such things pose no threat to our societies as a whole. It would be nice not to have these things happen, but there&#x27;s no possibility of succumbing to conquest.
