One of Obama's changes has raised the ire of British investment managers, bankers and stockbrokers. He wants them to collect tax revenue without compensation for their efforts.
Maybe he does somewhat study history. Capital always flows out of a country following a socialist revolution. If he does bully the rest of the world in collecting taxes from U.S. citizens who have invested abroad, they'll simply become citizens of another country such as Andorra or Monaco or form some offshore, dummy corporations.
Anyhow, there are more Europeans questioning President Obama's right to regulate their governments and financial institutions. This crack in European Obamamania will grow wider as more listen less to what the President says and learn instead from his actions.
