We are one of South Korea’s biggest allies. NK is still technically at war with SK. Their border is the most heavily guarded on the planet. The US has thousands of troops stationed in SK, Japan, The Phillipines etc…
The US leads an annual “war games” in the region, in which SK participates. NK views the annual war games as a practice invasion by the US and SK. Most of NK’s bellicose rhetoric is around the time of the war games.
In addition, NK’s leadership is aware of the US history of regime change, and their perception as a oppressive, tyrannical, dictatorship. (Which thy are.)
Their sabre rattling is mostly just that. Unless they can get consistently functional ICBMs, they pose little long term threat to the US. At least the US mainland…
Trump’s rhetoric only vindicates Kim’s paranoid calls for nuclear weapons, as a defensive weapon, or deterrent. Kim, like Trump, is a pathetic little man,with a childish ego, and little to no opposition to his incorrect thinking. Kim cannot stand the sanctions imposed on him, as they essentially mean that he is anything but a god ruler. Kim’s family worked hard to oppress, and brainwash their country’s people for their own advantage. They don’t like America “making them look bad.” Much like Trump, he has labeled all media,or criticism as false,in hopes of keeping from being held accountable for their own actions.
Now, Kim, and Trump will play a dangerous game with the lives of their respective people, and the world in general.
Kim is a bad person, who wants to do bad things, without interruption. The US is his biggest obstacle to being able to just do whatever he wants. So. Like Trump, he has knee jerk, stupid reactions to any scrutiny.. .
