I just hope that the Americans are not stupid enough to use Tomahawks against the DPRK. They should remember that unlike Syria, North Korea is a nuclear nation, and their missiles can reach targets located thousands of kilometers away.
I honestly believed that this will not end in a war on both sides. This is US saying to North Korea that they should think twice before launching another test because us(USA) will be watching your every moved. And they also have that in mind, they know North Korea has and will used nuke if necessary.
