Will trump's military option against North Korea work? Legal and political restraints

North Korea's nuclear weapons and missiles are an unprecedented threat to the security of the United States, which has never been attacked by weapons of mass destruction. Pyongyang's provocations irritated President Trump and led him to openly consider military attacks against North Korea. The possibility of armed conflict between the United States and North Korea increased as both sides exchanged aggressive rhetoric. Military attacks against North Korea are virtually impossible in a legal as well as a practical sense. They will bring only disaster to all involved, including the US. The best way to resolve North Korea's nuclear issue is to rehabilitate the multilateral channel for dialogue and then begin talks. What if President Trump, however, implemented military options against North Korea because of the nuclear weapons development? The focus of this essay is to explore whether Trump can adopt military options against North Korea and if so, what legal and political considerations he must take.
