Now I'm interested. One thing I wonder about is China's ability to fight the NK army in a conventional war. I imagine NK army has shytty equipment and arms but so did the North Vietcong. I read somewhere that NK holds military families hostage basically to prevent defecting of military members which may strengthen their resolve.
From all the imagery I've seen of NK, outside of Pyongyang, has been heavily forested hillsides and fields. Also from the short amount of information I've consumed about the Korean war, some of the most vicious battles and encounters were ambushes and attacks in the mountains and hills by NK and Chinese forces against SK and the US.
How equipped is the Chinese Army to invade the country and engage in a ground war? Especially given they have not ventured into the country with a military for 60 years? The best solution I imagine would be targeted toppling of NK leadership instead of engaging in a drawn out war.
Just spitballing here. Someone has to know more about this subject.
NK makes its own weapons and armaments and they're primarily based on Russian designs with some intel from Iran. They have a pretty decent Air Force that's stocked with MiG 25 and 29 air superiority fighters.
North Korea is a heavily tunneled country and a lot of their military facilities are bunkered to protect from direct airstrikes, matter of fact, they're so good at using tunnels and underground cover for warfare that they helped the Vietcong develop their system of tunnels that resulted in successful guerilla warfare with the constant flanking of US troops in Vietnam.
China knows what it's dealing with but I doubt a ground invasion would be successful without suffering substantial casualties but I agree with a previous post that China does not WANT a potential regional war potentially involving nukes at it's doorstep, allies be damned.
