Even the SKoreans have gotten soft. This is what happens when you let your enemies regroup for 50 years building up their artillery and long-range weapons capabilities and letting them aim the weapons at you. The US and SKoreans should have taken out the North 50 years ago when the North didn’t even have enough bullets to arm their soldiers. The only thing that is stopping the SKoreans from crossing the DMZ is the threat of NKoreans artillery raining down on Seoul, the SKorean capital with over 10 million people. The 1st 10 minutes and the city will be flattened and millions of people will be dead. That is not including the 10 nuclear devices they have. The SKorean capital is only 30 miles away from the DMZ.
