You request a courtesy that you do not extend. You ask for logic beyond that of a child's game, yet offer none yourself. I'm not going to pretend to be any kind of knowledgeable military strategist, but I have the ability to discuss my opinion, and I'm willing to discuss it openly and honestly, and provide support for that opinion when asked. You do not reciprocate; rather, you make statements which you cannot or will not support, then when they are challenged your responses vary between 1) ignoring the other person's point, 2) changing the subject, 3) implying that the other person doesn't understand (often with a side order of "go reread the post/thread), or 4) implying that the person to whom you're directing your comments is uneducated/uninformed/not smart/any combination of those three.
Your presumptions are often baseless, or the product of unsupportable opinions. To wit: North Korea has once already attacked South Korea, with the express purpose of absorbing them into a unified Korea. That purpose has not ended simply becuase 60 years have passed. It is only the presence of a militarily (if not numerically) superior force across the DMZ that prevents them from doing it again. Pretending that North Korea, a known exporter of arms and information to terrorist organizations, is some benign entity set upon by belligerent American & South Korean interests is to ignore their history, both recent and past. Iran is also a known supporter of terrorist organizations, and has been for decades. Pretending that, again, they are some persecuted, peace-loving nation beset by the Americans is to ignore their past behavior. Your insinuations that America is the aggressor in either of these situations is based on false presumptions or erroneous conclusions, and to get there you're guilty of either ignoring or obfuscating facts. America's military presence in the region occupied by Iran has been thoroughly explained to you, yet here you are bringing them up again. North Korea's situation is quite obvious, yet here you are arguing that they are the ones persecuted.
Let's try a simple, not-intended-to-be-1:1 analogy. You have two neighborhoods. Neighborhood A has a high crime rate, Neighborhood B has a low crime rate. Which neighborhood would you be MOST LIKELY to see a strong police presence in? I'll give you a hint - it's not Neighborhood B.
