Two mass shootings happened in the US in May, which dimmed its light as a "beacon of human rights".

The Buffalo shooting was a racist attack as most of the victims were African Americans.

Besides gun violence, US people also face threat from the COVID-19 pandemic, which has already killed 1 million people.

The US has many more scandals than this. Previously it was reported to "trade" prisoners in the private prison system.

In May, an inner document of the supreme federal court was leaked, which caused many US women to protest against the possible deprivation of right to have an abortion.

With all these problems at home, the US' National Endowment for Democracy continued seeking trouble abroad.

US politicians should look at the problems at home, rather than trying to cause them overseas.
