Obama did in fact aim and take action to reduce the US footprint abroad. He gave good speeches, but didn't actually do anything other than leave a vacuum.
Was that all he said? It's North Korea's 11th missile test this year and comes amid increasing frustration from Trump about the lack of progress in curbing Pyongyang's nuclear and ballistic missile programs. Soon after the launch, but before North Korea announced its unprecedented height, the US President responded on Twitter. "North Korea has just launched another missile. Does this guy have anything better to do with his life?" he asked, referring to Kim. "Hard to believe that South Korea and Japan will put up with this much longer. Perhaps China will put a heavy move on North Korea and end this nonsense once and for all!" Cherry-picking. A time honored profession amongst fruit flies.
There are ways to beat hair tests too, bit more complicated though. Urine tests though, just slip in a substitute.
