One thing a lot of people don't like about Donald Trump - but I do - is his willingness to point out that some people have done a pretty horrendous job when asked to deal with matters of great importance to this country. On the matter of North Korea, both the Bush and Obama administrations were either made to look like fools by the Kim dynasty or chose to punt on the matter because they weren't prepared for the possible consequences of decisive action.
That has resulted in nothing good. Today we have a petulant, irrational dictator in control of an at least in-development nuclear arsenal, firing missiles on whims and continually making threats of targeting the United States with ICBMs which may or may not be capable of delivering on his threats. In the meantime, the country is little more than a gigantic prison with primitive living conditions for those the government leaves alone, and a sadistic torture chamber for those it does not.
