I’m not clear on how exactly we’re “supporting” German/EU monetary policy
For example, when Obama met with Tsipras and informed him he would have no help from the U.S. in seeking to reform the EMU nor in negotiating a rational resolution to Greece’s debt crisis. The Obama administration was a staunch ally of austerity in practice. I’d guess this was driven by Realpolitik given that he wanted Germany’s and Brussels’ help imposing Russian sanctions. Sometimes you have to do Realpolitik. I get that. But let’s not pretend it didn’t happen.
ETA: Obama’s message to Tsipras was actually stronger than I implied above. It was more along the lines of “submit or else”.
