China's support of North Korea – geopolitical or economical
Military destruction is something avoidable, even negotiable. Afghanistan is an example, militarily obliterated, it is now a world ruled by the warlords, where the warlords negotiate in ‘bags of money' and ‘bags littered with weaponry'. They are happy with the negotiable deals they make. This is how military war goes on, promoting some, and demoting masses. On the crossroads of negotiation the masses are negotiated with cultivating all sorts of illegal drugs, cocaine and heroine are a few to reckon. On the crossroads of waging weaponry war, there is a way out to escape and progress. Afghanistan would not remain on the threshold of such failure as it is lucky to have sincere ‘politico-lords', though insincere ‘warlords'. Afghani politics is getting stable and mature by span of years.
Economic destruction ends up in nowhere. Economy once ruptured is hard to build. Europe after the Second World War was devastated and the way, means, and sincerity it took Europe to restore the guttered economy, is not only hard to find, but also difficult to follow in today's era. So, China's efforts to get hold over its neighboring states are all economical.
