Blake Stilwell, We Are The Mighty
It may not look like it anymore, but countries still invade one another. Ethiopia invaded Somalia in 2006 to stop Islamist terrorists from taking over the government.
Israel invaded Lebanon that same year to stop Hezbollah rocket attacks. America invaded Iraq because of the perceived threat of weapons of mass destruction.
The world's most recent invasions weren't really conducted with the idea of actually annexing countries.
Well, not lately, anyway.
There are many other powder kegs out there: India vs. Pakistan, Iran vs. Saudi Arabia, or China vs. all of its neighbors. But the Korean Peninsula is still the most volatile country vs. country situation, given the almost 70 years of animosity, the constant state of war (there was never a real end of the war, only an armistice — and North Korea pulled out of that in 2013) and the continued acts of violence between the two.
The threat of widespread destruction is the deterrent that keeps the conflict from boiling over.
It's important to remember that the 1950-1953 Korean War was a disaster for both sides, and that fact is largely what drives North Korean military policy. It's what keeps the people supporting the regime through animosity toward the US and South Korea.
"Over a period of three years or so, we killed off — what — 20 percent of the population," Air Force Gen. Curtis LeMay, head of the Strategic Air Command during the Korean War, told the Office of Air Force History in 1984.
Dean Rusk, a US secretary of state under Presidents Kennedy and Johnson, said the United States bombed "everything that moved in North Korea, every brick standing on top of another." North Koreans either remember the war firsthand or through the stories from their grandparents. Fighting between North and South Korean forces was particularly brutal, and as a result, there is no reason to believe either side would pull punches today.
Both countries have significant military power. South Korea has one of the most powerful militaries in the world, with 3.5 million troops. North Korea has 5 million troops with another 5 million that can fight in a protracted war. The North Korean songun policy means the military comes first in terms of food, fuel, and other materials before any are given to the population at large. Mandatory conscription (for a 10-year enlistment) means that most North Koreans have some form of military experience.
