What do the government of China, the government of Germany and the Republican Party have in common? They’re all trying to bully the Federal Reserve into calling off its efforts to create jobs. And the motives of all three are highly suspect.

It’s not as if the Fed is doing anything radical. It’s true that the Fed normally conducts monetary policy by buying short-term U.S. government debt, whereas now, under the unhelpful name of “quantitative easing,” it’s buying longer-term debt. (Buying more short-term debt is pointless because the interest rate on that debt is near zero.) But Ben Bernanke, the Fed chairman, had it right when he protested that this is “just monetary policy.” The Fed is trying to reduce interest rates, as it always does when unemployment is high and inflation is low.

And inflation is indeed low. Core inflation  a measure that excludes volatile food and energy prices, and is widely considered a better gauge of underlying trends than the headline number  is running at just 0.6 percent, the lowest level ever recorded. Meanwhile, unemployment is almost 10 percent, and long-term unemployment is worse than it has been since the Great Depression.

So the case for Fed action is overwhelming. In fact, the main concern reasonable people have about the Fed’s plans  a concern that I share  is that they are likely to prove too weak, too ineffective.
