Answer:
Kim Jong-Un
Step-by-step explanation:
Kim Jong-Un is a dictator because he obtained power via illegitimate methods, there is no mechanism to remove him from office, and he has the authority to impose nearly any policy he chooses, including the execution of his rivals or their banishment (together with their families) to dreadful labor camps.
You can be a dictator even if you support the US. The US supported a number of totalitarian governments throughout the 1960s and 1970s, mainly in Latin America, and these regimes were obviously highly pro-US.
