I can't stand him. He's an extremely superficial thinker, not one-fifth the writer his brother was.
He's "right-on" from a right-traditionalist perspective. He says things he thinks people will find shocking because he enjoys being thought of as an old curmudgeon. It's a psychological crutch, not a serious intellectual/political position. He enjoys being thought of as a bete noir, an enfant terrible. As a result he always seems to be scrabbling around for the most controversial and shocking thing he could say from a hard-right-traditionalist perspective.
Many of his proposed policies are completely idiotic, like his claim that if only we would "properly" punish drug users and dealers then we could win the war on drugs. First, we already punish them pretty harshly; anyone who cares to spend the time to read the caselaw will see that people are regularly put away for a term of years for possessing with intent to supply merely a few hundred pounds worth of heroin and crack. Two years for having £200 of crack is a bloody harsh sentence, and it's one that was imposed by an English court only a few years ago.
Second, there are plenty of countries that do impose the "proper" punishments for which he calls (Singapore, China), where people are executed for drug offences. And yet, those countries still have drug problems; how can this be? Well, it can be because Peter Hitchens is clueless on drug policy and has applied his evidence-free, superficial thought processes to that as to pretty much every other issue he writes about.
He also adheres to the scummy, anti-British / anti-Western alt-right foreign policy inclination (like Peter Oborne) that impugns the motives of the war in Iraq, that lauds Vladimir Putin as a visionary and generally demands an isolationist foreign policy that is completely at odds with this country's traditional foreign policy disposition. Whether we like it or not, we are the only middle-power with truly global capabilities. We still have a mini-empire (in the Mediterranean; Gibraltar at the western end and our Cyprus bases in the east), our base at Bahrain, our 3,000 Gurkha soldiers and the army establishment in Brunei, our territory in the Indian Ocean at Diego Garcia. Only France, among the other middle powers, has a comparable mini-empire.
Peter Hitchens has never been able to get over being Christopher's little brother, and it sent him a bit loopy. He clearly hewed to the opposite of whatever position his brother adopted, leaving him with a really quite nasty, reactionary set of ideas that manages to marry the worst elements of isolationism, superstition and barbarous socio-political ideas. He should be treated as the confused, psychologically-broken man he is.
