As tensions rise with North Korea the big question is will it lead to war? Well lets take a look at what has happened so far, The US has deployed the USS Carl Vinson aircraft carrier along with a group of battleships to Korean waters, Navy Seal team six has also been deployed in South Korea to take part in a training exercise simulating the assassination of North Korean leader Kim Jong Un. The joint defense facility Pine Gap near Alice Springs in Australia has been placed on high alert, the Australian government is concerned that the situation with North Korea will turn into a war.
China has stopped receiving coal shipments from North Korea. China does have an agreement to defend North Korea but has said that because of North Korea's nuclear program the agreement has been broken and they are no longer obliged to defend the country. South Korea has said that they do not believe that this will turn into conflict, but this definitely seems like they're saying this to try and calm their citizens and not create mass panic.
North Korea has warned of attacking the US at any sign of aggression, on Saturday the 15th of April is the celebration of the founder of North Korea Kim Il-Sung's 105th Birthday, it is believed the North will conduct a nuclear weapons test on this day. It is likely that the US will wait to see if China will do anything about North Korea before they take any action. This is the closest we've been to a war with North Korea for a long time and it is more likely than not that it will turn into one, if it does it will most likely happen shortly after the 15th of April.
