The US will export more natural gas to Europe so that it can stop buying natural gas from Putin.

Whether this hurts Putin depends on whether some other country will buy the gas he would have sold to Europe. I don't know, but I would not assume it is impossible.

The British royal family invested directly in transporting slaves to Jamaica. I would expect the same is true for other British colonies, including the ones that rebelled and became the United States.

I believe that Britain owes reparations to the descendants of those slaves.

The article linked to above displays symbolic bigotry by capitalizing "black" but not "white". (To avoid endorsing bigotry, capitalize both words or neither one.) I object to bigotry, and normally I decline to link to articles which promote it. But I make exceptions for some articles which give important information about racism or the fight to eliminate racism. That article is one of the exceptions.

Poland's partly-authoritarian government hopes that its strong opposition to Putin will shield it from EU pressure.

The two partly-authoritarian governments in the EU, Poland and Hungary, have protected each other from pressure through EU rules that require standards of democracy, and independence of the judiciary (often referred to in this context as "rule of law"). If Orbán is defeated in Hungary, the EU will be able to pressure Poland much more effectively.

The US is turning the job of schoolteacher into a low-wage job; many teachers are planning strikes.

The UK is not giving local governments enough money to repair 3000 damaged bridges. They also struggle to provide housing and welfare benefits for the people of their district.
