The US government has always relied on the cooperation of other countries to maintain the dollar's preeminent position. But international patience is wearing thin, especially as the carrot-and-stick approach of recent decades has become all stick and no carrot. If President Obama and his successors continue with their heavy-handed approach of levying sanctions against every country that does something US policymakers don’t like, it will only lead to more countries shunning the dollar and accelerating the dollar's slide into irrelevance.
