Uh, we invaded Iraq and absolutely destroyed the country and decimated the population - because we were going to be &quot;greeted as liberators&quot;.<p>Certainly the people of North Korea need liberators, even if it takes them a few generations to appreciate it.<p>South Koreans don&#x27;t need to be saved, North Koreans do.<p>However the entire world should be doing the liberation, not just the USA. In fact for once maybe they can leave us out of it and just tell China &quot;end this&quot; or we&#x27;ll destroy your economy by not buying anything from you for as long as we can.<p>But hell, look at Syria and the refugee crisis. Imagine if Assad had nuclear weapons.
