We do not know yet.
I don't think so, not when the US is on South Korea's side with the largest amount of nukes in the world.
No. The US leads the world in enforcing sanctions against North Korea.
North Korea attacked South Korea.
probably because north Korea is probably going to cause trouble and send nukes to us.
The US isn't really doing anything in North Korea at this time. There are no formal diplomatic relations between the two countries; North Korea is still technically at war with the US and South Korea (although the US never actually declared war on North Korea). North Korea is notorious for its desire to keep foreigners out, and its borders are well guarded. North Korea also refuses to accept trade or even foreign aid from the US. However, North Korea has a large military and nuclear weapons, and their friend and neighbor China is very powerful, so the US does not have the option of militarily attacking North Korea. So there really isn't much going on between the two countries, except occasional threats or small scale military actions. Hatred of the US and its allies is a major propaganda that the North Korean military uses to keep itself in power, which is why you often hear about North Korea threatening the US, South Korea and Japan.
No North Korea is a humanitarian nightmare.
Yes North Korea does not like the US mainly because of the country's involvement in the Korean War between North and South Korea.
Yes the US is known as the American Empire to North Korea.
The US is not permitted to patrol North Korea, nor do they. The US military does however have military bases in south Korea as part of a treaty to protect them against a possible attack by North Korea.
The US was part of a United Nations force fighting North Korea and its allies.
North Korea is not going to bomb the United States. North Korean War Ministers and Generals know that any attack on the US will result in North Korea being flattened into a pancake.The posturing is for a diplomatic response. The North Koreans have always desired bilateral negotiations with the United States because they believe that those negotiations would be more prestigious as well as giving them more benefits. The United States has always demanded that North Korea engage in six-party talks (US, N Korea, S Korea, Japan, China, and Russia) in order for the other countries to limit North Korean demands and come to a regional consensus. The North Koreans think that if they are crazy enough, the USA will give into their demands.
