April 2012 was the first time, but it has happened sporadically since.
I don't think so, not when the US is on South Korea's side with the largest amount of nukes in the world.
South Korean system is similar to that of the US. North Korean system is similar to that of Hussein's Iraq.
The U.S. has thousands of nuclear weapons. It could probably turn the entire world, to say nothing of North Korea, into a nuclear wasteland if it felt like it.
No. The US leads the world in enforcing sanctions against North Korea.
North Korea attacked South Korea.
No, they used two on Japan but none on Korea.
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.
North Korea would retaliate by sending artillery shells at Seoul, South Korea and within 2 hr. the largest city in South Korea will be leveled. North Korea would also deploy their troops across the DMZ and invade South Korea. In response to the artillery the US will be forced to bomb the artillery guns and defend South Korea's border. China will also step in and aid North Korea by cutting off trade to the US and readying their nukes to fire on South Korea, Japan or the US. The US would loss respect in the eyes of the world for this attack and this may cause Iran to attack US allies ultimately plunging us into WWIII.
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.
