Let's bring out the big guns: Presidend Obama addressed the global community directly in his op-ed that appeared in dozens of newspapers around the world.  His meassage?  We need a global, coordinated, robust economic stimulus measures.  This is a little preview of what the conversation will be like during the G-20 Summit in London next week.  So far, Ol' Europe has politely declined U.S. overtures urging its governments to spend more money.  We'll see if Angela Merkel and Nikolas Sarkozi are able to resist the U.S. President's charm in person. China first!  Beijing issued a proposal to replace U.S. dollar as a reserve currency with a new "international reserve currency" controlled by the IMF.  No word on whether the Chinese will peg the yuan to the new reserve currency, just as they have been doing with the dollar. Buy America update.  Alan Tonelson of the U.S. Business and Industry Council argues it's a good thing, while the new Treasury publicc-private partnership investment program insists on it.  Just wondering, why is no one ripping the Treasury to shreds for tis "horrible" protectionism?  Could it be a cultural bias against people who make things for a living?
