You can decide if you think we should intervene,but if we do then how should we help?
There are a number of things we could do such as vote for a resolution in the UN against China,try to help the peaceful protests in Hong Kong or make sure the protests stay peaceful.
If Britain votes for a resolution in the United Nations then China might want to change their behavior so that the rest of the world will not feel as if they are doing bad things . In contrast, because China is so powerful, they might not care about the vote and just carry on as they are doing.
Trying to help the peaceful protests could lead to China taking action against us, which means that this might not be such a good idea. But we could tell the protesters that we agree with them and urge them to stay peaceful.
You can decide!
