I didn't mention nukes in the post or intend to....Nuclear Blackmail is another subject Nk and China especially may use,,,
India and Pakistan could and I wouldn't put it past Israel either...But thats not necessarily about dictators and a further reach..
China and NK are enough when it comes to nuclear blackmail
I mentioned 'dictators', lots of those and if they have a smaller nation next door, who is to stop them.....Condemn them yes...
With nukes, just pose a couple drills before you act and the world will get the message.....A change from the defense posture used with nukes historically....
We used Nuclear Blackmail on China during the Korean War...It held China back,,,,But we Still split Korea rather than stay at war with them....China didn't hesitate to enter the Korean War, hence the 38th parallel https://history.army.mil/brochures/kw-chinter/chinter.htm
