MANILA - President Rodrigo Duterte has lamented that Filipinos seem to be too hard to satisfy, as he again blasted his critics.

In a speech delivered before Israeli businessmen in Jerusalem on Tuesday, Duterte said he has dealt with communist and Moro rebels and the drug scourge, but “the most problematic also is the Filipinos itself.”

“There’s --- you cannot do good. It’s always wrong. And so we will just have to navigate where democracy allows us space to work and produce results,” Duterte added.

The President did not expound on what he meant by his statement, but throughout his speech he lamented how some Filipinos, especially the rich, would get “offended by my behavior.”

“They are not my enemies but I do not like --- I do not mix with rich people. And they are the ones who are almost offended by my behavior,” he said.

Apart from his war on drugs, the President has earned criticism for his brash language, but the chief executive said he does not pay attention to this.

“And so I have a bad mouth. I curse, I throw epithets a lot when I'm angry. They say that, "you know this Duterte is not a statesman. He should not be going to anywhere, he will put us to shame. He talks like a gangster and he curses everybody.’ Correct. Because I never studied to be a statesman, there's no course of a statesman,” he said.

“I studied law. I grew up in a place where there's just a lot of trouble, until now. And our paradigm seems to be far different from the cultured ones in the -- especially the four hundred of society, the elite," said Duterte, the first Mindanaoan elected President.

Duterte won the elections in 2016 on a platform of eradicating criminality, illegal drugs, and corruption in government, edging out his closest rival Mar Roxas by over 6 million votes.

While his remarks in speeches continue to draw controversies, Duterte remains popular among majority of Filipinos, although the latest survey of major pollster Social Weather Stations showed that his net satisfaction rating dropped to a new personal low of +45.
