What is the point of having troops and military bases in South Korea?
The  reason I ask is because North Korea is not a threat.  North Korea’s  million-man army may look impressive on paper, but remember that Iraq  had a million-man army, which also had modern equipment, combat  experience, and plenty of fuel.  In contrast, North Korean soldiers  suffer from malnutrition and rarely train due to a scarcity of fuel and  ammo.  Most North Korean soldiers could not attack because they are  needed to defend the entire DMZ and coastal approaches (they remember  the 1950 landing at Inchon) while entire divisions must remain  throughout North Korea to fend off heliborne offensives, food riots, and  probable coups On the other hand, the entire 700,000 man South Korean  active duty army can be devoted to the defense of Seoul.  The modern  South Korean army is backed by over 5,000,000 well-trained reservists  who can be called to duty in hours.  South Korea has twice the  population of the North, thirty times its economic power, and spends  three times more on its military each year.  South Korean military  equipment is first class whereas most of the North Korean military  equipment is over 30 years old and much is inoperable due to a lack of  maintenance.  If war broke out, South Korea has a massive industrial  capacity and $94 billion in foreign currency reserves to sustain a war,  while North Korea has no industry and no money.  As a result, South  Korea is roughly five times more powerful than North Korea. South Korea  could crush North Korea in a war without our help.  North Korea's  military equipment that date back to the  1950,60,70s,80s which are  Soviet obsolete weapons system that are not properly maintained. North  Korea is unstable and could commit suicide by attacking South Korea.  North Korea attacking south Korea would be like a bully punching a man  in the face that has a loaded gun. So if all of this is true,why do we  have military bases in South Korea then? South Korea has mined and built  concrete fortifications along the mountainous DMZ to make a rapid  breakthrough impossible.  More importantly, China and Russia trade  heavily with South Korea and provide no help to the fragile regime in  the North. I mean come on there is a Burger King on the DMZ. So what is  the point of having troops there? Many of you guys make very good points. But technology wise they lag  behind. South Korea has military that is just as large as North Korea  and better trained. Yes they would use a lot of arty on Seoul but in the  end they would be smashed,crushed and defeated in a another war. Maybe I  need to reserch more but South Korea is five times more powerful then  NK.

First,  I'd like to introduce you to your new best friend, the paragraph.  Second, you have outlined an impressive set of facts and logic.  If North Korea were to start a war, a LOT of people would die, and since  Seoul is only 30 miles from the DMZ, it would still be hugely  disruptive to the South Korean economy, which is now tightly linked with  the world economy.

I have never thought of it that  way.  If that's the case then there is no reason for the US to be there,  since South Korea can easily defend itself.

Because  North Korea is a danger to one of our closest allies in the region,  despite your failure to recognize it as such....and because that close  ally has requested that we maintain a presence there.  What you must understand is that the North Koreans are not aware of  anything that you state is "on paper."  From an early age they are told  that they are superior and that they are surrounded by enemies who are  jealous of them.  They are conditioned to be ready to fight...and they  ARE ready to fight.  The main reason you cannot see the threat is that you are applying  rationality to what has been proven to be one of the more irrational  regimes in the world.

Perhaps you are unaware that the  Korean War is still ongoing.  We are in a protracted cease-fire.   Further, the government and the leaders in North Korea want to unify the  peninsula, but only under Communist rule.  As to the concrete fortifications and minefields, these are (as Patton  said), "[Fixed fortifications] are monuments to man's stupidity."  When I  was in South Korea, several tunnels large enough for ten abreast to  walk through were discovered under the DMZ.  North Korea is constantly planning and scheming to take over the South.   And with the current political climate, with the Obammessiah's World  Apology Tour, the North doesn't think the world has the stomach to stop  them if they decide to invade.

North Korea has special  forces that dug caves under the DMZ and tried to kill the president,  Park Chung Hee, at the Blue House. The American are there to patrol the  DMZ. North Korea are testing nuclear missile and South Korea doesn't  have an anti-missile defense so the Americans are there to provide them  with one. Amercains have bases there just in case if North Korea  violates the cease fire. Also North Korea are now making their own  weapon and tanks and they are getting weapons from China and Russia  secretly.

You have researched your numbers but have  left off some very glaring facts.  1.  You cannot compare apples to oranges..Numbers of Iraqi troops cannot  be compared to numbers of NK troops for many reasons      a. will to fight are different for each army...NK troops think of  their leader almost as a god; not a tyrant      b. topography and local advantage      c. artillery and underground facilities (solid granite; not sand)  NK has enough arty pointed at Seoul to level it in about 2 hours.  Put  another way, imagine 9-11 wiping out all of NY in 2 hours 2.  How would 700,000 troops defend Seoul against artillery?  have you  ever been to Seoul?  BTW, a large portion of that 700,000 are just guys  doing their 2 years because they have to..many don't want to be  there....again will to fight 3.  NK SOF troops...largest SOF force on the planet....very well  trained...will use all types of unconventional ways to cause trouble. 4.  Sleeper agents in SK 5.  DMZ is the most heavily mined border on the planet....not that many  troops needed to defend it.  Add to that the tunnels that have not been  all discovered under the DMZ that NK could use 5.  NK has huge chemical weapons stockpile and a handful of nukes (wind  always blows north to south over there)  As to your food riots and such.  most in NK believe that the US and SK  are the cause of those shortages...another reason for them to fight China has been and will continue to provide NK support to keep them  stable regardless of their trade with SK  I could go on, but as you can see, everything is not as you think. You  should research more before making assumptions.....joining the military  wouldn't help either
