Okay, on to the Guardian article, which does well to quote the original content.
>When the students poured into Tiananmen Square, the Chinese government almost blew it. Then they were vicious, they were horrible, but they put it down with strength. That shows you the power of strength. Our country is right now perceived as weak … as being spit on by the rest of the world—
Honestly, I don't know what that means - it's bordering unintelligible. The way he used pronouns in that sentence completely obfuscates who he was calling vicious and who he was calling strong.
So, I can go with how I feel about Trump as a person and use the Guardian as my source for how I should interpret what he said: "he praised the Chinese regime". Or I can just go with what I really feel which is "I have no idea what that means."
