So far, he has done a great job, despite opposition from a lot of powerful sources. Even the European Union and the former United States president Barack Obama were against him. But he is determined to finish the job which he has started.
What do you consider a big job? I don't see any results from activities of Duterte. His goal was not a drug, and the building of a totalitarian regime. For this reason, it is supported by Russians and for this reason, it is nothing but misery will not bring to the Philippines.
Ahh... here we go again. For Ukrainians like you, the major issue here is the support he receives from the Russians. If you know the Russian mentality, then you won't be surprised. Russians respect people with strong will power. That is why they abhor Obama and respect Duterte.
